Not sure if I should post here or elsewhere (is Tomcat considered NetWare or "web")?

Anyway, this showed up on the logger screen (in NetWare) and anything that used tomcat refused to work:

org.apache.tomcat.util.threads.Threadpool logfull
SEVERE: All threads (250) are currently busy, waiting. Increase maxthreads (250) or check the servlet status

I've never seen this before on any server we've had.

Any ideas?
