Re: Failing FastCGI PHP

I'll start by compiling php with --enable-debug

At the moment I get backtrace results like this:

#0  0x48c7d95b in memcpy () from /usr/lib/libc_r.so.4
#1  0x8977280 in ?? ()
#2  0x10 in ?? ()
#3  0x894e500 in ?? ()
#4  0x894dc00 in ?? ()
#5  0x8962000 in ?? ()
#6  0x8960200 in ?? ()
#7  0x894e4e0 in ?? ()
#8  0x894e4c0 in ?? ()
etc etc etc...

Thus useless :P


At the moment it has been running remarkably stable for a few days. So now and then a failure. Probably because of a request being given to a php-fastcgi process handling a slow upload of a file... :-/

Hi,

I have made a apache setup with PHP running as FastCGI (apache 2.0.58,
mod_fastcgi 2.4.2, php 5.1.4)
PHP is called directly as FastCGI without a wrapper script.
On a given moment the PHP FastCGI application reaches
dynamicMaxClassProcs. After that happens the PHP FastCGI application
totally crashes and can only be recovered by restarting apache.

PHP Crashes with:

"terminated due to uncaught signal '10' ((null)), a core file may have
been generated. "


Are you able to get a core dump and what does it show? Here's some
doco on how to get a backtrace:

http://bugs.php.net/bugs-generating-backtrace.php

That will give us some clues on whether it's php or fastcgi..
