mysqld still crashing

[Ben Clewett]

Hi MySQL/Oracle,

A while ago I posted that my mysqld was crashing about once a week. This is still the case. I wonder whether any member may have an idea why?

Using 7.2.10 on Linux 3.1.10-1.9.

Only a single NDB table at abut 50 DML/sec from various clients.
Table with 227 columns, 5 keys, 6567 rows, and average row length of 884 bytes.

Table schema, information schema report and MySQL crash stack trace to follow.

Because Cluster keep crashing, it's giving cluster a bad name in this company. Which is a shame, as I want this to work. If anybody has any ideas, please let me know.

Regards, Ben.

Crash log:

05:54:07 UTC - 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=8388608
read_buffer_size=5242880
max_used_connections=37
max_threads=200
thread_count=34
connection_count=34
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 2058485 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...
