My guesses: Your application has bad sync locking between some threads, which is causing one thread to block the others.
Your application has bad database access code, which allows one thread to block others while waiting on the DB. Your application is disk bound, and the single long process is hashing the disk drives so much that is has dragged down the rest of the OS, making it very slow to respond to the IO request of the other, small tasks. You haven't configured the GC well - however, I would expect this to cause sporadic problems, rather than continuous ones. There are numerous JVM tools out there to help you with all of these issues - from the simple garbage collection monitor that comes with java (JConsole http://java.sun.com/developer/technicalArticles/J2SE/jconsole.html) to full blown tools like JProfiler (which last I checked, had a free trial) --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
