I currently use
Apache/2.2.23 (Win64)+mod_fcgid/2.3.7 (x64) + mod_ssl/2.2.23+OpenSSL/1.0.1c + PHP5.2.17(x86).
4-5 times a day I get an error like this:

Code:
Faulting application name: httpd.exe, version: 2.2.23.0, time stamp: 0x5037670b
Faulting module name: libaprutil-1.dll, version: 1.4.1.0, time stamp: 0x5037679a
Exception code: 0xc0000005
Fault offset: 0x0000000000001023


Exception and offset are always the same, Apache gets itself restarted (code 255), hosted sites work as they should.

Additionally, there is a corresponding event in WER-Diagnostics log:
Code:
Possible heap corruption detected (exception code 3221225477). Initiating further diagnostics.


Could you please help me to find out what the reason is?[/code]

PHP 5.2.17 is really old and certainly is not compiled with OpenSSL 1.0.1c. If possible, do not mix SSL versions.

I am not sure about mod_fcgid (x64) loading PHP (x86), but others on this forum might know it.

If using pure mod_fcgid php solution it doesn't metter which PHP version with which OpenSSL Version since it runs separated.

However upgrading PHP won't hurt.

Yeah but the hosted sites are really old and poorly documented, so I guess it's better to let it be, as long as it's just a log entry and everything runs fine.

Anytime you have a mismatch between Apache & PHP, mod_fcgid is the way to go.

As you can see, I already use it.
BTW, those crashes certainly have something to do with EnableSendfile. I turned it off, and there are no crashes so far.

OK, it seems like the problem is solved, though download speed dropped significantly. Luckily, there are no large downloads.
