You need to read the mod_jserv documentation carefully and make sure that
mod_jserv specific parts of your httpd.conf are configured for one JVM and
not 8.

Alternatively, you can set AjpManual (something which sounds like this) to 
"on" and start only one JVM manually. This is explained in the documentation.

Unless you use something decent like IBM JDK, most Linux JVM have pretty
bad performance compared to their commercial counterparts. See volano mark
benchmarks on the net.

Also, consider Jakarta (http://jakarta.apache.org) instead of GNU jsp.

PS: In Linux, a thread = process. So if your JVM is spawning threads, you 
may see them as processes in ps.
