If they are both on the same server then almost surely the issue is swapping or
CPU overcommitment. That said, additional information from your logs, if
germane, may shed more light on this incident.

Ok, i'll go take a look. They are both on the local server so network
issues shouldn't be a cause. Cheers though, i'll go look at the JIRA link.
If I find anything else i'll post here.
thanks
