--- Comment #5 from Johannes Weberhofer <[email protected]> 2011-06-15 18:42:22 UTC --- It's quite small. select count(*) from categorylinks; shows a total of 21 lines. I'm sure it's a mysql bug; I have digged the mysqld-log and found the following: 110615 10:17:14 [Note] /usr/sbin/mysqld: ready for connections. Version: '5.1.51-ndb-7.1.9a-log' socket: '/var/run/mysql/mysql.sock' port: 3306 SUSE MySQL RPM 110615 10:19:56 - 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. key_buffer_size=16777216 read_buffer_size=262144 max_used_connections=1 max_threads=151 threads_connected=1 It is possible that mysqld could use up to key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 133916 K bytes of memory Hope that's ok; if not, decrease some variables in the equation. thd: 0x1479d30 Attempting backtrace. You can use the following information to find out where mysqld died.
