Cache issues?

[Migrated From Jforum.net]

I've got one forum in one category for which any new posts disappear until I refresh the cache. I can't repeat it on any of my other forums. This started after I posted a pretty long message with images and embedded HTML. Strangely a sticky post in the same forum posted a while ago never disappears - only things after this one large post.

Has anyone else seen something like this? I can repeat it at will by posting something to any thread after the "big" post thread. Any debugging ideas?

2.1.5 installed from the distribution (i.e. not CVS). PostgreSQL 8.1, Tomcat 5.5.15, 1.4.2_08 JDK, Fedora Core 3.

I looked at the log4j.xml but it had C:\ in it which didn't work too well on my Linux install I'm going to try to crank up some debugging to see if I can figure out what is going on.
