Hi Howard,

The move to linux was part of a move in-house for our client as the web
services are only accessible behind the firewall.

My gut feeling is that the issue isn't related to the WS as they run on a
scheduled task 3 times a day. I think the issue lies in our app and
struggling with not being able to see exactly what's happening during the
crash. JavaMelody provides some insight but just not enough.

I'm quite happy to post the charts for others to see. Just not sure what
the best way to do it is.
