Did you set the minimum heap size for the application? and maximum? Too many threads in JVM 1.4.1 is a known limitation - you need a newer JVM with non blocking IO - apparently recently release

WAS 3.5.3 does not use the 1.4.1 JVM but I would suggest increasing the heap size. look for the JVM mx and ms options. Also, run -verbosegc to watch the garbage collection
