    Hi,

    We are running java process (server) on several Operating systems, only on AIX
    , this process is having 100's of kernel threads after few days of running most of them in sleep mode.

    As per Java debugging guide, it either because of bug in software or bug in JDK.

    We are using 64 bit JDK on 64 machine machine/kernel.
    Does this needs any tuning ?

    Are there any kernel setting that will terminate these sleeping kernel threads, say in 2 hours etc automatically.
