Re: Limitations regarding InstanceMaxRequests and IdleTimeout IIS6 fcgiext 1.5

bg — Sun, 18 Oct 2009 10:23:05 GMT

Dear WenJun Zhang,

Thank you for answer. It was indeed the application pool´s idle shutdown feature that caused the shut down of the idle processes.

I have now created a new application pool for my RoR site, trying to find settings that give acceptable performance for my application. Avoiding idle timeout of the Ruby processes in my pool helped to some degree but I have so far not been able to prevent the processes from dying after about 120 requests, regardless of the load I put on the IIS. So this is still a major problem.

The typical behaviour when testing the site with low load is a response time, when a ruby process in the pool starts, of 10 seconds. The following consecutive requests render a response in 90-120 ms, until the process dies and starts over. One Ruby process occupies about 35 Mb of memory, and there is plenty of memory on my server to accommodate many Ruby processes at the same time. During my resent tests I have limited the number of instances to 4. (MaxInstances=4)

In my application pool I now run with these settings:

Recycling panel:
Recycle worker processes (in minutes): unchecked,
Recycle worker processes (number of requests): unchecked,
Recycle worker processes at the following times: unchecked,
Memory recycling: Maximum virtual memory: unchecked,
Maximum used memory: unchecked

Performance panel:
Idle timeout: unchecked,
Request queue limit: unchecked,
Enable CPU monitoring: unchecked, maximum number of worker processes: 4

Health panel:
Enable pinging: checked,
Enable rapid-fail protection, unchecked,
Startup time limit: 100,
Shutdown time limit: 90

Fcgiext.init:
ExePath=D:\ruby\bin\ruby.exe
Arguments=D:\rails\Ruby\public\dispatch.fcgi
IgnoreDirectories=0
IgnoreExistingFiles=1
QueueLength=1000
MaxInstances=4
InstanceMaxRequests=100000
IdleTimeout=43200
StderrMode=IgnoreAndReturn200
ResponseBufferLimit=8388608
EnvironmentVars=RAILS_ENV:production

Are there any other settings I could try to manipulate in order to make my ruby processes survive more than 120 requests, even at low load conditions (two requests per second)

I really would appreciate suggestions how to resolve this problem.

Thanks.

IIS 7 Windows Server 2008 R2 Ruby On Rails

vecchia — Tue, 01 Sep 2009 06:42:12 GMT

Hi all,
i'm sorry for my bad english but i don't speak it very well. I'm using Windows Server 2008 R2 in trial version and i'm configuring IIS 7 + FastCGI + Ruby On Rails but i'm having issues. I tried to search on google and here but all links go on a old site with a removed guide. I've installed ruby and it works with webrick but i need to use IIS. So i put into

C:\inetpub\wwwroot\ruby-app

my ruby application and i added the fastcgi module to the website:

iis manager -> site -> handler mappings -> add module mapping

Request path: *
Module: FastCgiModule
Executable: C:\Ruby\bin\ruby.exe|C:\inetpub\wwwroot\ruby-app\public\dispatch.fcgi production

all it's ok, i can run the site but when i try to run the ruby application i retrieve this 500 error:

HTTP Error 500.0 - Internal Server Error

c:\ruby\bin\ruby.exe - The FastCGI process exited unexpectedly

Detailed Error Information

Re: Where is RubyforIIS (rubyforiis.sosukodo.org) has disappeared!

It's strange that the site is down. Unfortunately, this component is required. For now you can try the version that I downloaded from that site last summer.

http://ruslany.net/download/RubyForIIS-0.1.exe

For install steps you can also refer to this blog post: http://ruslany.net/2008/08/ruby-on-rails-in-iis-70-with-url-rewriter

Ruby and Ruby on rails support on IIS 5.1 IIS 6.0

paggy4u — Fri, 28 Sep 2007 11:10:59 GMT

Hi,

Currently Ruby and Ruby on Rails is facing lots of limitation while working with Mongrel, WebRick and up to some extent on Apache. The Ruby community is also facing the hosting problems without the proper support from Windows.

Working and configuring Ruby on rails perfectly with Windows XP is also not Possible.

Now since this FastCGI has arrived as a sign of big relief, we expect the IIS Team to look more deeply in this matter and offer us a working solution as soon as possible. This support will also boost IronRuby developers, who are currently busy learning Ruby on Windows.

Thanks

Simultaneous requests to Rails

chrisortman — Wed, 05 Sep 2007 17:04:40 GMT

I've managed to get a rails app working under IIS using FastCGI, however I've run into a bit of a snag. As a test I have a client program send 10 simultaneous requests to the same rails page (simple render 'hello world')

However when I slowly ramp up and get 10 ruby processes sitting idle on the webserver I can get all 10 simultaneous requests to complete successfully. I'm not sure if I would want a way to always have at least N workers or if there needs to be a way to get ruby.exe to start faster?

Thanks

dfunky — Tue, 04 Sep 2007 22:26:00 GMT

I followed "10 steps to get Ruby on Rails running on Windows with IIS FastCGI" to get my app running on two different W2K3 servers.

Everything went fine with the first installation but I just can't get it work on the second server. I've repeated the steps over and over and I still get the same error:

Error 0x80004005 occurred processing request.

The FastCGI process exited unexpectedly

This is what I get in the fastcgi.crash.log after trying the test controller:

The only thing that went different from the first installation to the other was the "MSVCR71.dll was not found" error I got durring the 2nd install. Still the "require 'fcgi'" instruction resulted to true so I assumed to installation was ok...

Please help me !

Re: Having trouble setting up RoR, FastCGI and Longhorn Beta 3

zopal — Sat, 01 Sep 2007 17:36:31 GMT

I'm trying to setup Ruby on Rais on IIS7 FastCGI (LH beta 3) as well, without success.

I have no idea how to pass arguments to the ruby.exe, that's maybe the part of the problem. If I just add the argument to the handler mapping I get the following error:

<add name="Ruby" path="*" verb="*" modules="FastCgiModule" scriptProcessor="E:\ruby\bin\ruby.exe E:\ruby\myapp\public\dispatch.fcgi" resourceType="Either" />

An unknown FastCGI error occured
Error Code 0x8007010b

If I just run the ruby.exe:

<add name="Ruby" path="*" verb="*" modules="FastCgiModule" scriptProcessor="E:\ruby\bin\ruby.exe" resourceType="Either" />

E:\ruby\bin\ruby.exe - The FastCGI process exited unexpectedly
Error Code 0x00000001

Hi Derek,

The steps on my blog are for IIS6 only unfortunately, there are a couple of issues that prevent RoR from working on Vista / LHS FastCGI. It is missing the extra support we added to the IIS6 version to allow RoR's "serve the static file if there, otherwise serve the Ruby script" functionality.

However, you should be able to set up the Vista/LHS version of FastCGI to request your RoR controller script directly. Can you post the error you are receiving so we can take a look at it? If you need help getting to the detailed error, please see Troubleshoot IIS7 errors like a pro.

Also, be sure to set up permissions that IIS needs to access Ruby, and Ruby needs to access your application files: give Network Service read/execute access to the directory with Ruby executable, and your Ruby application files.

Thanks,

FastCGI with Ruby on Rails - IIS 5.1 / IIS 6 - Http POST issue.

mspeight — Fri, 15 Jun 2007 01:30:51 GMT

I have got IIS and Multiple App's to talk using same technique’s as I used with isap_fcgi.dll, all works fine apart from an intermittent problem.

After returning data from a POST, the rubyw.exe process is left in some funny state, and the next request causes rubyw.exe to exit.

The same request may work 3 times, then crash on the 4^th.

Steps are as follows POST -> Returns a Redirect -> GET on Redirfect fails to return (ruby.exe exits) -> Browser has another go new instance of ruby.exe started and page returned

Other Steps are POST -> Returns just render_text -> Another browser instance goes to url -> No page/error is returned (i.e. the new request got to rubyw but it crashed)

I have duplicated this with a simple form, that posts and returns itself.

It seems to be a timing thing, But I cant figure out the cause.

PS: I have patched the cgi.rb (To remove the IIS reference, if you don’t you get random crashes ay any time)

Anyone come across this before.

-----------------

By set-up is detailed here http://mspeight.blogspot.com/2007/05/how-to-run-multiple-rails-apps-under.html (but uses fcgiext.dll instead of isapi_fcgi.dll). I did need to repatch the "AbstractRequest:request_uri" differently as this FastCGI does provide REQUEST_URI

Re: Support for other application frameworks

Mike,

Thanks for the response!

Before your response I had posted about this to the rails core team mailing list (I am not on the team, just on the list) and it has recieved some response, so you may want to check it out (it's a Google Groups mailing list):

http://groups.google.com/group/rubyonrails-core/browse_thread/thread/b88ad36ddd82477e

I would love to test, and help however I can. Is there a more recent version than the 'technical preview' I have already downloaded? I am a Mac / Linux guy, and am a bit shaky in Windows, but I am deploying my site on Windows Server 2003 so I need to learn it. Right now I am using mongrel as the webserver because it 'just works'. But I need to find a better solution because mongrel has no NTLM authentication module.

Thanks,

Peter
