What could cause these Apache crash errors ?
- by jacobanderssen
Hello guys.
I had a server crash several days ago. I use Cacti to keep stats: at the time when the server crashed, a huge spike from Load 1 to Load 200 occurred, with over 800 processes in the run queue ( from 300 average).
Upon checking /var/log/httpd I notice this:
* glibc detected /usr/sbin/httpd: double free or corruption (out): 0x00002b8f3142c2f0 **
Followed by alot of these:
[Sat Mar 13 19:20:20 2010] [warn] child process 3090 still did not exit, sending a SIGTERM
[Sat Mar 13 19:20:20 2010] [warn] child process 3091 still did not exit, sending a SIGTERM
Followed by this:
======= Backtrace: =========

/lib64/libc.so.6(cfree+0x4b)[0x2b8f1463c73b]

/etc/httpd/modules/mod_file_cache.so[0x2b8f1cdf00fb]
======= Memory map: ========
And finally a lot of these:
[Sat Mar 13 19:20:27 2010] [error] could not make child process 733 exit, attempting to continue anyway
[Sat Mar 13 19:20:27 2010] [error] could not make child process 24560 exit, attempting to continue anyway
[Sat Mar 13 19:20:27 2010] [error] could not make child process 31384 exit, attempting to continue anyway
I am also noticing one or two lines like this:
[Mon Mar 15 01:17:26 2010] [notice] child pid 20765 exit signal Segmentation fault (11)
Please help me shed some light on this.
Thanks !
