Server process jstart.exe unavailable

Hi gurus,

I am not an administrator but a developer, so the question may be naive.

We have a local NW installation for development. After upgrading to EhP1, the jstart.exe process always becomes unavailable after some operations (maybe adding a user, sometimes just opening the portal). I guess it may be caused by out of memory issue but do not know how to diagnose. Can someone point me out where to find some clues? For example any log files to dive into? Or any diagnostic tool? Thanks a lot.

B.R.

    Hi,

    Please check the dev_jstart,dev_server0,std* files(for corresponding j2ee processes).Also check the latest default trace files(present in j2ee/cluster/serverx/log)

    As it involves jstart,I presume you are having 710 j2ee.

    Plz post the latest errors so that we can have a look.

    Regards,

    Abhishek

      Hi,

      java.lang.OutOfMemoryError: PermGen space.

      Please check the value of the parameter -XX:MaxPermSize in the config tool.If possible increase it(128-->256) and restart the engine.

      Check the SAP note recommendations for setting this parameter accordingly.

      SAP NOTE #Note 723909 - Java VM settings for J2EE 6.40/7.0 can be helpful.

      Hope it helps.

      Regards,

      Prasanna

    Hi Lee,

    Please go through the SAP note 634689.

    Normally one doesn't need to set the Permgen space usually the MaxPermSize takes care of it.In your case I feel you can try out with increasing the Max perm size according to the memory constraints of the server on which java is running.I'll post more info if I find any

    Regards,

    Abhishek

    I increased the PermSize up to 384M since Perm heap is always out of memory. But the engine can not start with this configuration. Then I decreased the heap size dwon to 896M and keep PermSize as 384M, because when Perm heap is out of memory, the Old Gen is only 25% full. It can be started now. I will see whether it can live longer now. While the configuration looks weird: the Perm Gen is too big when comparing to the Old gen...

    The server is much stable than before. While when we deploy components frequently during development and test, it will also crash. Seems like undeploying a component will not release the PermGen memory it uses. So the memory usage will keep increasing with more deployment.
