LiveCycle, Email Service Stops working

Hi Folks,

I'm having a sporadic issue with LiveCycle. Roughly 2-3 times a month the email service will stop working. Users can still email our adobe mailbox and wont receive any errors back but their documents arent being sent back to them. Once i restart the Jboss service the application will start working again and process the backlog. Has anyone experienced this issue? I've copied an extract from the log from the last time this issue occured.

thanks

Tony
