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.
 
To report this bug, see http://kb.askmonty.org/en/reporting-bugs
 
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: 5.5.34-MariaDB-wsrep
key_buffer_size=134217728
read_buffer_size=131072
max_used_connections=20
max_threads=153
thread_count=20
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 466777 K  bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

Hi Dieter,
Could you please provide us with the table structure and some sample data (records)?

Hi Nirbhay.
Thank you for the reply.

I would provide sample records, but it should not be publicly visible.
Access to cluster is also available.

Hi DIeter,

I am still not able to reproduce this issue.
Can you please post a test case which leads to this problem?

Comment by Nirbhay Choubey (Inactive) [ 2014-06-20 ]

Hi Dieter, Did you notice a similar crash lately? If so, can you try it with the latest server version?
