This seems to be one of those errors that won't go away. In this case, it may be a case of human error.

First of all, here are a series of links with similar error messages on Shutdowns

They all have seem to have one thing in common: MySQL for Windows.

It was claimed that Bug 7403 (the second link) was fixed and patch implemented July 14, 2005: http://lists.mysql.com/internals/27091

The versions of MySQL that this fix should be in 4.0, 5.0.40, 5.1.42. Looking in the error log you posted, I see you are using MySQL 5.1.67. Apparently, no one knows how to fix this issue or wants to (http://bugs.mysql.com/bug.php?id=7403) I also noted that the error messages indicate that you are using MySQL in Linux already.

I have three(3) suggestions that range from the most passive to the most aggressive...

SUGGESTION #1

Try setting log_warnings to 0, if you don't mind flying blind on warnings.

SUGGESTION #2

Upgrade to MySQL 5.6.11. Hopefully, there is should be more updates and bug fixes for this.

SUGGESTION #3

Move the Database to Linux. There should be more stability for this problem away on a better machine with the most updated kernel for the OS.

Give it a Try !!!

The past of least resistance would be SUGGESTION #1: Setting log_warnings to 0 and restarting mysql. – RolandoMySQLDBA Apr 29 at 1:59
ok will do with suggestion #1 but what effect it will havecon mysql box will i stop to receive warnings? – biz14 Apr 29 at 2:06
some say is due to table corruption what is your opinion on this? – biz14 Apr 29 at 2:11
