server error

[so_2]

Hi All
I ahve an hpux server running HP-UX B.11.00. It is in a clusterd configuration with another server. There is one package configfured and is SAP.
When SAP users try to loging on the application they are getting "logging error ABAP RUNTIME ERROR CUREENT ABAP TERMINATE NO SPARE TO LOAD. INCREASE SIZE OF AREA USED TO STORE 4 PROGRAMS
".
But at the same time I am able login to the server and do normal diagnistics. There are no problem found with cluster or package nor there was a problem in performance.

SAp team says it is a memory leak problem and advised me to reboot this server. The reboot solved the problem but I am not sure why the problem occured.
If anyone give me a clue of what the error message points to? Also how can we check the memroy leak problems on a HPUX server?

Thanks in advance

So,

Purify and Insure ++ are two tools used to check for memory leak on applications, for more info refer to this doc:

ftp://hprc.external.hp.com/memory.htm#checking_for_app_memory_leaks

Also you might want to talk to your development team if any.

Regards,

Jaime.

Hi,

To see the size of shared memory segments:
# ipcs -ma

Track SAP's usage over time.

Shalom,

The SAP team led you down the path.

Of course rebooting the server solved "the problem"

The real issue is the application and/or the OS are allocating memory and not giving it back when done.

The most common cause of this is the application itself being poorly written. The solution is to patch it.

A number of OS patches deal with memory leak/allocation issues. Staying current on bi-annual patch releases (boring, rather watch grass grow but its why we have jobs) will generally help you avoid OS induced memory leaks.

Hi S.O,

I agree with SEP, patching is most crucial part of any OS. Are you in sync with current patch level of HP-UX and SAP? Memory leak can occur from an application either. If you are familiar with debugging tools, give a shot.

Thanks all who replied. I will check the patch levels as SEP suggested.

Also i will try using tools Jaime have mentioned. Thanks a lot agian.
