J2EE Engine in Status: some processes are running

[Former Member]

Hi!

I installed a SAP ERP EhP4 system via system copy and have problems with J2EE Engine.

The ABAP stack starts without any problems.

The J2EE stacks seems to have some problems/errors, because the J2EE state is either "J2EE: status info unavailable" or "J2EE: some processes running".

Enclosed the content of log file "std_server0.out":

Any helpful information will be very appreciated!

Hi Jgen,

If you still get the same error even after following the recommendation as per note, you can do a reboot of the server and try to start it again. In some case, a normal reboot of windows clears out memory and problems get fixed.

Hi,

Can you try by below values

Heap Size: -Xms2048m

MaxPermSize=512m -XX:PermSize=512m

Also have a look at SAP Note 759669 - java.lang.OutOfMemory - the system is out of resources.

Hope this helps.

Thanks,

Hi!

Many thanks for your reply. I checked the Java settings within Configtool recommendation in sap note 723909 and they are:

I am on Windows 64:

1) Heap Size

Actual value for Heap Size: -Xms1024m

recommendation for Heap Size: -Xms1024m

2) Permanent Space

Actual value: -XX:MaxPermSize=512m -XX:PermSize=512m

changed to: -XX:MaxPermSize=256m -XX:PermSize=256m

recommendation for For 7.0 on 64 bit: -XX:MaxPermSize=512m -XX:PermSize=512m

Unfortunately this does not help

Thank you!

regards
