Comment 1 for bug 509350

Crash seems to follow immediately the following log line(s) on joiner: "100108 16:30:16 [Note] WSREP: SST kill local trx: 2888".

Some stack traces:

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=8384512
read_buffer_size=131072
max_used_connections=9
max_threads=151
threads_connected=3
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 337741 K
bytes of memory
Hope that's ok; if not, decrease some variables in the equation.
