Devmon Turning Purple

All,

We have hobbit and devmon deployed and running for the last 8 months with no problems, then all of a sudden devmon stops reporting to hobbit. It casuses hobbit to turn purple. The devmon process seems to be still running, it just stops reporting to hobbit. If we stop and start the devmon process, its ok for 4 or 5 days and dies again.

Any one else having this issue? No changes were made to the server, it just came out of the blue.

Thanks, michael
