Hi,
 
I have installed MariaDB 5.3 from the apt packages on a lenny amd64 machine.
Initial setup went fine and the database is working correctly. When I give some
load to the machine I get crashes about every 8 minutes.
 
This is what the log shows:
Jul 29 00:36:17 svn mysqld: 110729  0:36:17 [ERROR] mysqld got signal 11 ;
Jul 29 00:36:17 svn mysqld: This could be because you hit a bug. It is also poss
ible that this binary
Jul 29 00:36:17 svn mysqld: or one of the libraries it was linked against is cor
rupt, improperly built,Jul 29 00:36:17 svn mysqld: or misconfigured. This error
can also be caused by m
alfunctioning hardware.
Jul 29 00:36:17 svn mysqld: We will try our best to scrape up some info that
will hopefully help diagnose
Jul 29 00:36:17 svn mysqld: the problem, but since we have already crashed, some
thing is definitely wrongJul 29 00:36:17 svn mysqld: and this may fail.

Just to confirm the installed packages: 
dpkg --get-selections | grep maria
libmariadbclient16                install
mariadb-client-5.3                install
mariadb-client-core-5.3                install
mariadb-server-5.3                install
mariadb-server-core-5.3                install
 
Any pointers?
 
Cheers,
