Hello,
We recently encountered an issue where the MySQL server stopped responding to all connection requests and current queries. Thsi included connections on the server itself, e.g. MySQL Administrator.
We could not stop the MySQL service and needed to restart the server.
Our system:
- Windows 2008 Standard SP1
- 64-bit OS
- MySQL version 5.1.34
- Virtual Guest on VMWare ESX 3.5
- RAM assigned = 22 GB
- innodb_buffer_pool_size=14000MB
- InnoDB
- file per table
below is the excerpt from the MySQL Error Log.
Any help in diagnosing this problem would be appreciated.
--start error log---
101123 9:01:28 - 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=57671680
read_buffer_size=65536
max_used_connections=212
max_threads=550
threads_connected=198
It is possible that mysqld could use up to key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 237235 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...
