Subject: fb1 /var full after reboot, caused all sorts of problems 

/var on fb1 filled up today, which caused all sorts of CDS issues.  I found out about the problem by reading the logs of the services that were having trouble running, in which they complained about not being able to write to disk.  I looked at the filesystem status with 'df' and noticed that /var was full, which is where applications write temporary data, and will always cause problems if it's full.

I tracked the issue down to multiple multi-gigabyte log files: /var/log/messages and /var/log/messages.1.  They were full of lines like this one:

Seems like something related to the gpstime kernel module?

Anyway, I deleted the log files for now, which cleared up the space on /var.  Things should be back to normal now, until the logs fill up again...
