[Bug 1159748] [NEW] Ramdom apache2 crash in Ubuntu 12.04 (libpthread-2.15.so)

[Juan Pablo Marco Cardona]

Public bug reported:

Hello,
in one of of ubuntu 12.04 servers the apache2 crashes ramdomly.

This is the last apach2 crash in the kernel log:
[1110685.354122] /usr/sbin/apach[10514]: segfault at 6c ip 00007fde00a44e84 sp 00007fff1eb1f7e0 error 4 in libpthread-2.15.so[7fde00a3b000+18000]

Maybe it is not related, but when the apache2 process crashes, in the access log there are this entries:
127.0.0.1 - - [24/Mar/2013:06:42:29 +0100] "OPTIONS * HTTP/1.0" 200 126 "-" "Apache/2.2.22 (Ubuntu) (internal dummy connection)"
127.0.0.1 - - [24/Mar/2013:06:42:29 +0100] "OPTIONS * HTTP/1.0" 200 126 "-" "Apache/2.2.22 (Ubuntu) (internal dummy connection)"

I have attached an apport crash report with the this bug report.

Thanks in advance.

Regards,
Juan Pablo
