Hi Bhargav,

Hope you are doing good.

When the engine goes down due to heap issues, there are 2 main steps inorder to resolve the case:

1) Make sure that the j2ee parameters and the server on the whole is configured correctly so that optimum performance can be obtained.

2) If 1) does not help, there may be a application causing a memory leak. We need to identify this and fix the issue.

If you face the error again, kindly check the below link to generate the heap dump.

Please have a look at:

SAP Note No. 1004255- How to create a full HPROF heap dump of J2EE Engine

If you wish to analyse yourself, more details are available in SAP note 1883568 and:

Hi All,

Thanks for the information

Not able to navigate in NWA.

We are getting 500 service timeout error after clicking on any tab in NWA(after approx. 10 mins) .

Any suggestions regarding this

Hi Bhargav,

No problem

Most likely we will need to optimize the server  (dispatcher or ICM) depending on your release.

As this is a different issue, please raise a new thread in "netweaver administrator" forum.

Hope this helps.

Hi Bhargav ,

Seems to be a memory issue

Check in the MMC whether  full garbage collector is running frequently .

What is the memory consumption in the server ?

What is you OS/DB ?

Check the dev_server0 trace file in the work directory

Thanks ,

Manu

Hi Bhargav,

You'd better follow note 1004255 and troubleshoot the OOM error, if you have not done that yet.

Create an incident if necessary.
