	A guess, two actually.
	Guess #1. Your server is low on memory and swapping. Look at
the usage of the swap file. If it is non-trivial then add memory.
	Guess #2. The Java part of things is starved for memory too,
typically is appetite for stack space. You may need to tune both
Java and Tomcat for more available memory, and maybe more available
threads to handle requests through them.
	We presume you do not compress files. We presume your virus
software is fleet of foot and not dragging the system to its knees.
