MySql server crashes
Port 3306 getting locked (Port 3306 getting locked (server has to be rebooted to acquire the port again)
One of the tables is corrupted

Attempt to fix the table repots access denied for roo@localhost  to database information_schema.

System Info:
OS: Win2003 (Microsoft Windows [Version 5.2.3790])
It is a 2 cpu Xeon2.7GHz with 3.65GB of ram
	C# client built on top of C api (libmysql.dll)

1.	Initially I was running two services that bombarded mysql with inserts and selects. Ratio of inserts\selects is 1\10. (Later I figured even one is enough to kill mysql.)
2.	Some of the inserts were invalid. They included columns not corresponding to table schema.
3.	Half of the inserts used insert  with update option
4.	Inserts updated 3 tables 2 MyISAM and 1 Innodb
5.	Innodb is the one that is getting corrupted
It was a question of minutes to kill the mysql server

I fixed inserts. All the inserts are proper now. That didn’t help much. Mysql server still crashes; it takes though longer 1-2 hours instead of minutes

Log/error log don’t show anything that could shade some light. Server dies quietly

Here the errors I see on the client side:
1.	Lost connection to MySQL server during query
2.	MySQL server has gone away
3.          Initialy I was using 4.0.7 version of libmysql.dll/that got changed I moved to 5.0.13 version. Well it is still craching

So far I am unable to reproduce the problem using mysql-debug with debug option I'll keep on trying

How to repeat:
I don't have a good test case yet. I'll try to write one if time allows

Suggested fix:
No idea
