OutOfMemory in EP6 SP2


I am running on EP6 SP2 Patch 3 HF4. I have about 100-200 users accessing the EP in an hour. We have start up the EP Dispatcher and EP Server as windows services. We are having a OutOfMemory error everyday and the whole EP would crash (i.e. SAP J2EE Engine Server service stop running). We have to restart the SAP j2EE Engine Server service everyday.

All the SAP Notes regarding OutOfMemory have been read thoroughy and implemented but this memory problem is still outstanding. We do not have any custom iViews in the EP, mostly the iViews from the Business Packages for MSS and ESS.

Here is our service.ini file :














Service_1_JavaParameters=-Dmemory.manager=1280M -Xms1280M -Xmx1280M -XX:MaxPermSize=192M -XX:PermSize=192M -XX:MaxNewSize=256M -XX:NewSize=256M -XX:SoftRefLRUPolicyMSPerMB=1 -classpath ".;.\system-lib\boot.jar;.\system-lib\jaas.jar;"\java.policy -Dorg.omg.CORBA.ORBClass=com.inqmy.system.ORBProxy -Djavax.rmi.CORBA.PortableRemoteObjectClass=com.inqmy.system.PortableRemoteObjectProxy -Djavax.rmi.CORBA.UtilClass=com.inqmy.system.UtilDelegateProxy -Djava.library.path=D:\usr\sap\EPPD\j2ee\j2ee_00\os_libs



Service_0_JavaParameters=-Dmemory.manager=64M -Xmx64M -Xms64M -classpath ".;.\system-lib\boot.jar;"\java.policy -Djavax.rmi.CORBA.PortableRemoteObjectClass=com.inqmy.system.PortableRemoteObjectProxy -Djavax.rmi.CORBA.UtilClass=com.inqmy.system.UtilDelegateProxy

Any help would be greatly appreciated....

    Could you post the stacktrace you get when you have an outofmemory exception (should be in the console logs somewhere)?

    Alternatively, try making a thread dump as described in note 599539 when you see the memory usage is increasing dramtically.

    This sort of question is very well suited for an OSS.

    Sorry to Poke in between, but we too are facing the similar issue in our Portal.

    The Systems crashes after throwing the OutOfMemory exception.

    The Situation used to occur twice a week,

    For this issue, we have upgraded the JDK version on the UNIX server.

    after JDK upgrade now its like weekly once.

    In short there is a bit improvement in the performance. But the issue has not resolved completely.

    So I just want to know are you still facing the issue. If no then what fix was applied.
