Hello mysql list

I posted this problem to the list earlier this month:

Error reading packet from server: Out of memory (Needed 6560 bytes) (
server_errno=5)

I was then told to upgrade to the newest version, which I did and which
seemed to solve the problem. Today, I got this in my log:

080521 14:18:22 [ERROR] Error reading packet from server: Out of memory
(Needed 2848 bytes) ( server_errno=5)
080521 14:18:22 [ERROR] Stopping slave I/O thread due to out-of-memory
error from master

Now, not only does it report an error, it also stops the slave process
instead of auto re-starting it as it did in version 5.0.45 (which I used
before). So all slave machines do not replicate until I manually start
the slave again.

What can I do about this problem?

Dominik
