Re: innodb keeps crashing due to out-of-memory errors

We have been trying everything we can to solve this crashing of mysql with no luck so far..

we have removed all other applications from the server, so it is a dedicated mysql serve.
we did a memory check, all seems fine
we have modified and tested the my.cnf with all possible combinations
we rewrote all the slow queries
we have updated mysql to the latest version (10a)

but mysql keeps on crashing every hour or so.

does anyone have some other sugestions? we are getting desperate...

thanx

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=67108864
read_buffer_size=2093056
max_used_connections=19
max_connections=70
threads_connected=10
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_connections = 351975 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...
Cannot determine thread, fp=0xbfe5e548, backtrace may not be correct.

New value of fp=(nil) failed sanity check, terminating stack trace!
Please read http://dev.mysql.com/doc/mysql/en/Using_stack_trace.html and follow instructions on how to resolve the stack trace. Resolved
stack trace is much more helpful in diagnosing the problem, so please do
resolve it
