blank displays

[Larry Barber]

I'm seeing some odd behavior on hobbit, (4.2.0). About once a week all the
displays go blank, they don't show any of the hosts. At the same time
hobbitdboard becomes empty, or nearly so. The hobbitd log shows:

2010-04-18 18:00:00 Ran scheduled task 8 from x.x.x.x: disable lnx1.* 240
Disabled by: auser @ y.y.y.y
Reason: yada yada yada

2010-04-18 18:00:00 Fatal error in select: Bad file descriptor

2010-04-18 18:24:22 Setup complete
2010-04-18 18:25:24 Setup complete
2010-04-18 18:32:39 Setup complete

Where the multiple "Setup completes" are the result of hobbitd crashing and
automatically restarting. Stopping hobbit completely and then restarting
appears to cure the problem. It does appear to be related to using the
scheduled disable function of Hobbit.

Any ideas about what could be going on?

Thanks,
