Description:
------------
Hi,
Myself and my colleague are trying to debig a problem which we have with a brand new server and setup. The server is Windows 2012. PHP 5.4.14 and wincache 1.3.4.0 have been installed via Microsoft web platform installer. The system is running IIS8. For the most part its fine but for the past week intermittently on a daily basis the following error is thrown for no discernible reason.

The behavior which illustrates the error is that IIS8 refuses all requests and the IIS8 logs show many 500 errors of many differing kinds but the following dump in the event viewer seems to be always the same. I would appreciate any help you can give us on this. Thanks.

Identical issue here - 0xc0000094 is a divide by zero error.

Based upon the fault offset, it looks like a fault in php_wincache!utils_getindex() when the numfiles arg is 0.

Unfortunately, the utils_getindex() function is called from all over wincache.  So, without a crash dump (or minidump) with the full callstack, there's not a whole lot I can do with this bug.

If you get a crash dump, please let me know!
    --E.

Hi all, this was a problem we encountered on Woindows 2012 R2, and php 5.5.18.

Wincache was 1.3.5.0 and in essence we were seeing the below in some respects;

Faulting application name: php-cgi.exe, version: 5.5.18.0, time stamp: 0x543ed3aa
Faulting module name: KERNEL32.DLL, version: 6.3.9600.17056, time stamp: 0x532a2e6c
Exception code: 0xc0000005
Fault offset: 0x00019072
Faulting process id: 0x9008
Faulting application start time: 0x01d00254b6a9c4f1
Faulting application path: pathhere\php-cgi.exe
Faulting module path: C:\windows\SYSTEM32\KERNEL32.DLL
Report Id: f4623cc2-6e47-11e4-80c6-0225b5010b0b
Faulting package full name: 
Faulting package-relative application ID: 

Disabling Wincache, seems to have stopped a lot of the errors coming through. Can you advise on what you would need to look at this?

Thanks

Current version of WinCache (1.3.7.1) has numerous fixes to potential crashes, esp. in the startup code path.  Closing this very old bug.
