Does anyone know, if this is a bug? We have upgraded 2 slave machines to Percona Server 5.5 from standard MySQL 5.1.53 and suddenly the server stability has gone away. We have 1 crash on both machines in the last 24 hours.
The output:
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=104857600
read_buffer_size=131072
max_used_connections=37
max_threads=2000
thread_count=16
connection_count=15
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 4478321 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…
