Scheduled disable causes crash?

[Johan Sjöberg <johan.sjoberg (at) deltamanagement.se>]

Hi!

During the last month, we have had some problems with Xymon when using scheduled disabled (added from the web interface).

The first problem we had was on September 17th, when hobbitd crashed while/after running the scheduled disable. We got the following error in hobbit.log
2010-09-17 05:00:00 Fatal error in select: Bad file descriptor
2010-09-17 05:00:00 Setup complete


After that incident, I enabled verbose logging for hobbitd, and turned up the logging for some other process as well. This morning at 06:00 we had a new scheduled disable. This time hobbitd just stopped logging after running the disable. The web interface did not work correctly. When clicking a test, an "Internal server error" message was displayed. Also, the bbgen test went purple (last update at 05:59:26).

The only errors I have been able to find in the logs are in bb-display.log:
2010-10-05 06:00:26 xstrdup: Cannot dup NULL string

2010-10-05 06:40:54 xstrdup: Cannot dup NULL string

Xymon was restarted at 06:43.
Here is the hobbit.log from the time. It was too large to paste in the mail.

We are running Xymon 4.2.3 on CentOS 5.
