Description
The server crash in loop (restarted by mysqld_safe), it's
a shared hosting with more than 1000 databases, but always sames
request seems to crash the serveur (always phpwebgallery).
Full crash report that I can see in my syslog file :
130322 11:04:00 [ERROR] mysqld got signal 11 ;

This could be because you hit a bug. It is also possible that this binary
|
or one of the libraries it was linked against is corrupt, improperly built,
|
or misconfigured. This error can also be caused by malfunctioning hardware.
|
|
|
We will try our best to scrape up some info that will hopefully help
|
diagnose the problem, but since we have already crashed,
|
something is definitely wrong and this may fail.
|
|
|
Server version: 5.5.30-MariaDB-mariadb1~wheezy
|
key_buffer_size=2147483648
|
read_buffer_size=1048576
|
max_used_connections=15
|
|
|
max_threads=502
|
thread_count=1
|
It is possible that mysqld could use up to
|
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 3132316 K bytes of memory
|
Hope that's ok; if not, decrease some variables in the equation.

Attempting backtrace. You can use the following information to find out
|
where mysqld died. If you see no messages after this, something went
|
terribly wrong...
