Subject System load creeping up with Tomcat + Lucene
Date Thu, 03 Mar 2005 17:21:20 GMT

I'm using Tomcat and Lucene to build a search engine. I suspect this
is a Tomcat problem, but I can't be sure.

The system load and CPU usage by Tomcat keeps creeping up with
http-8081-Processor<n> threads becoming stuck in _hpiThreadHardSuspend
in For example, I might get 10 or more threads similar to
what I pasted below.

Any ideas?
