Phantom /var full messages

I'm running snort 2.1.3 and mysql 3.23.58 on FreeBSD 4.9 RELEASE. All
applications are built from ports.
Periodically I get /var full messages and everything comes to a grinding
halt. The problem is, /var isn't full.
df -h will show /var at 104%, but du -h /var shows /var at 40% (for
example). If I shut down snort and mysql, wait for a minute and then start
them back up, df agrees with du again.
The system works fine because only /var is full (although things can get
squirrelly if I let it go long enough because the system can't write to the
logs or the mail spool), so I can still ssh in and run utilities.
I suspect this is some sort of filehandle not being released issue, but I'm
not sure how to track it down. I've got lsof installed, but I'm not an
expert on it yet.
Any hints would be welcomed. What's the best way to troubleshoot this
