Out of memory error, server restarts itself

[Former Member]

I know this has been reported alot and I have gone through thread after thread.

In my trace file I get the following error

#1.5#00127943773C005A0000000E000008D500042BA14D51A29A#1173871693776#com.sap.engine.frame.Environment##com.sap.eng

I have set my memory parameters for 64bit hardware (HP-UX on itanium) as follows

Whenever I go into UME configuration through the browser I the server restarts itself.

Any further ideas. This particular LPAR is shared by quite a few systems, but we are not seeing any OS memory issues

Hello Fenton

You should run a few (3 or 4) thread dumps whenever you experience

the system hanging.

Please see note 710154 for how to create a thread dump.

You should then review defaulttrace files for both the dispatcher and the server.

If you need help reviewing the logfiles, please open an OSS message with SAP.

Thanks

Kenny
