Hi ,

I am trying to bring up a EP system , and i am getting the following error in my dev_sdm and dev_dispatcher logs ...

Dears,

I have the same problem using Dual Stack installation , Abap+Java with kernel 720. pl 201, it's the latest release.

The note 1285016 match the problem but it's for kernel 700 only, and in any case we already have the latest kernel.

Any advise ?

regards

After stopping the instance, did you notice any other process for SIDADM running?

Also tell us if any changes were done prior to restart?

HI,

Check SAP Note 1285016 - Java engine terminates spontaneously with double stack

I have seen that note ... but mine is a EP system (Java Only) so not sure if its applicable in my case .

You should always have latest kernel on your system , irrespective of Runtime Engine (ABAP or JAVA).

So go ahead and upgrade kernel to latest available for your release.

HI,

Gagan is right.

Update your kernel and try again, is the solution for the issue. In JAVA Stack you use JSPM for kernel update.
