Description:
MySQL crashed last night with no apparent error. I'm not sure if it was related but the nightly mysqldump was running at the time. See below for stack trace:
pure virtual method called
terminate called without an active exception
04:15:02 UTC - mysqld got signal 6 ;
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=402653184
read_buffer_size=262144
max_used_connections=300
max_threads=800
thread_count=38
connection_count=38
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 2245822 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...
