Which Tomcat version are you using? How to reproduce the problem?

In SystemGlobals.properties / jforum-custom.conf, did you chage the servlet extension to .html? The default is .page

I'm starting to get this error a lot - happens about twice a day now. Restarting the application fixes it, but it seems to be getting more frequent.

We're using Tomcat 5.0.19 on java 1.4.2_03-b02, with MySQL 4.0.18

I can provide a stack trace if needed, but it looks the same as the one above - this happens when viewing the main page. When we try to view a post at this point, we get a seperate NullPointerException:

Assuming you're running jForum 2.1.8, that error line indicates that the SmiliesRepository is returning a null and not a Map of the Smilies... not sure why that would happen.
