Solaris msgs alert not clearing

I'm having a problem with a Solaris client. A msgs alert was triggered over 2 hours ago, and it still has not cleared, even though no new alert-worthy messages have appeared in the message log. Has anybody else seen this behavior? I'm running a 4.2.0 server, I'm not sure what the version of the client is since I don't have access to the box involved (Henrik, it might be a good idea to include the Hobbit client version in the client data).

Thanks, Larry Barber
