Description:
I have installed MySQL server 5.1.46 on Windows Server 2008.
The SSL cert is used for this instance. SSL works fine. But some times server crashes with exception
100429 15:00:01 - mysqld got exception 0xc0000005 ;
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=209715200
read_buffer_size=2097152
max_used_connections=27
max_threads=10000
threads_connected=14
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 1958544 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...

The manual page at http://dev.mysql.com/doc/mysql/en/crashing.html contains
information that should help you find out what is causing the crash.

The SSL was generated with using instruction http://dev.mysql.com/doc/refman/5.0/en/secure-create-certs.html.
[mysqld]
ssl-key=C:/OpenSSL/bin/server-key.pem
ssl-cert=C:/OpenSSL/bin/server-cert.pem
ssl-ca=C:/OpenSSL/bin/ca-cert.pem
How to repeat:
Use SSL for MySQL server. It seems that issue happens at opening SSL connections with MySQL server, but this happens not for each connections.
