 A lot of us have this problem, I think its a known-bug.

We just setup a crontab to restart once an hour.

Let us know if you figure it out, michael

Devmon is hanging for me, on average once per day. No error messages
anywhere that I can see, no entries in the log, nothing.

All the processes are present.

The 'fix' is to kill the master, wait for all the child processes and the
master to exit, and restart. I now have a hobbit extension script checking
the last dm status and killing devmon if the update was over 4 minutes old.

What can I do to get a better handle on the error?
