:-) .... when you remove some load and the problem goes away:-):-).
How much memory/swap is used when these messages get queued and not processed?

I'm currently trouble-shooting a problem which does the same thing and have tracked it down to the memory running out ie. mostly swap being used while CPU's aren't (load average goes to 12 and 13 because of the heavy swap usage).

I'm organising more memory for the server at the moment, which should resolve the issue.

Regards,

Michael.
