I am having a few minor issues since upgrading. I'm currently running 6.0.3_GA_1915.UBUNTU6 on an Ubuntu 6.06 box. The issues are:

- Sunday afternoon the web client starts throwing "A network service error has occurred" and users can't login or use the client until doing a 'zmcontrol stop && zmcontrol start". Then it's fine until the following Sunday. This happens sometime around 1:45PM or so.

- mailbox.log and audit.log are both empty, which makes diagnosing the first issue kind of difficult.

Other than that everything else seems to work fine.

Any ideas?
