[debian-mysql] mysql replication issues since security upgrade

To whom it may concern

I originally sent the below email.

Since then,we actually realised the problem was bigger than we anticipated. We thought it was a memory issue, so therefore I sent an email to the Mysql mailinglist ( Please see http://lists.mysql.com/mysql/227047 (see the stack trace too)), to try and deal with it.

But the problem still persisted.

We then thought it was faulty ram, we therefore replaced the hardware.

What's actually interesting is that we then setup another server with Mysql 5.1.49 (i.e. before the security upgrade).
We then got replication working, and then after a 'soak period', continued to upgrade to 5.1.61, and as a result we started getting 'mysqld got signal 6' messages.

I sincerely hope im making sense, for this had been carrying on for quite some time.

If you can help anyway, it would be appreciated.

Kindest Regards
