  • w3wp.exe crash - faulting module iisfcgi.dll

    Aug 08, 2013 01:08 PM|networkengineer49|LINK

    I am running a shared hosting web farm with 3,000+ websites,  as I load more and more client websites using wordpress on top of PHP v5.3, i see more and more errors like this

    Faulting application name: w3wp.exe, version: 7.5.7601.17514, time stamp: 0x4ce7a5f8

    Faulting module name: iisfcgi.dll, version: 7.5.7601.17514, time stamp: 0x4ce7b85c

    Exception code: 0xc0000005

    Fault offset: 0x000070d3

    Faulting process id: 0x3f40

    Faulting application start time: 0x01ce94480840b41e

    Faulting application path: C:\Windows\SysWOW64\inetsrv\w3wp.exe

    Faulting module path: C:\Windows\System32\inetsrv\iisfcgi.dll

    Report Id: a71ad58a-0043-11e3-8a26-00155d1e434


    analyzing the dump file returns this issue:


    Unhandled exception at 0x730b711b (iisfcgi.dll) in WERBE76.tmp.mdmp: 0xC0000005: Access violation reading location 0x00000000.

    iisfcgi.dll!File_listener::HandleChangeNotification() + 0x154 bytes


    Can i get an idea where to go from here to resolve these errors?

    I share app pools with about 20 sites in each.  The app pools effected seem to be random and fail in groups when this error occurs.
