      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.

      where mysqld died. If you see no messages after this, something went
      terribly wrong...
