Description:
trying to partition a table into about 800 partitions, but it failed with out of memory as well as crashed the server.
I am working on a 4Core 4gb memory 1tb hdd server, so the server should be able to fit in more data than shown.
070704 17:41:29 [ERROR] /usr/sbin/mysqld: Out of memory (Needed 57688 bytes)
070704 17:41:29 [ERROR] Out of memory; check if mysqld or some other process uses all available memory; if not, you may have to use 'ulimit' to allow mysqld to use more memory or you can add more swap space

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=536870912
read_buffer_size=20967424
max_used_connections=11
max_threads=151
threads_connected=7
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 2515169 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...

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
