  Application Pool Recycling but not releasing locks... Reply Contact Hey All   A tool we use programmatically creates/updates ASP.NET 2.0 websites and each website is in its own Application Pool, this is all done via C# and DirectoryServices. When I create the website for the first time, I check to see if the related appPool needs to be created and do so if needed, if not, then I just recycle the application pool and regenerate my website DLLs in the bin directory. My problem is that even after recycling the application pool, my website's generated DLLs cannot get copied into the BIN directory as the old lock still exists on the old DLL files. If I wait a long time (couple of minutes), everything seems to work. In an earlier iteration of our code, we generated all websites within the DefaultAppPool application pool and never had any problems with locked files. Any ideas?   Thanks Mustafa

  Re: Application Pool Recycling but not releasing locks... Reply Contact So your problem is that your old worker processes are not going away for a while when you recycle your app-pool?  This would normally mean that some request is taking a while to finish (or even never finishing) - this could be caused by any code within the worker process (including possibly your code) - you will need to debug the worker process at the point when you have issued a recycle but it is still not going away - and get product support involved if you cannot debug it yourselves.

Reply Contact Since we do not know what code in the worker process is causing it to not exit on app-pool recycle, there is no way to tell if that code will allow the worker process to exit on app-pool shutdown.

Reply Contact Hello again everyone, I've gone so far as to actually delete the websites in question as well as their related app pool and I still cannot overwrite the assemblies in my website's BIN directory. I'm really hitting a wall here; any tips to solve my problem are very much appreciated.   Thanks.
