memory exhaust on SLES 10 SP1 ECC6

[Former Member]

Hello dear forum members,

We have ECC6 running on SLES 10 SP1.

Kernel : 700 patchlevel 146 created in : Linux GNU SLES-9 x86_64 cc3.3.3

The database runs on a seperate server.

The SLES box has 12 GB extended, 8 GB dedicated to ECC6.

When SAP starts all is fine, but in st06

in the memory/history it shows that every hour the

average free memory diminishes.

TOP on OS level shows that the shown values in ST06 are correct.

SAP appears to release the memory correctly.

This goes on untill approx. 300 MB EM is left. This takes around 2 days.

Then the system starts paging untill it runs out of swap space (slowly but surely using more and more of it) until the system finally freezes.

The only note I can find is 724140 but I am not sure if it will solve the problem.

Has anyone had a similar experience or a good idea where to look for a solution?

Many thanks

Dear forum members,

Linux ran on a VM (VMware)

The configuration was not according to note 1122388 and the mentioned VMware white papers.

To (drastically) resolve all issues, a choice was made to move to a different box, not in a Virtual Machine anymore.

This solved the memory issue.

Kindest regards

We changed the solution so the question now is not valid.

Many thanks and kindest regards

Dear Han,

could you explain what you did? Myself and probably all the other readers of the forum are interested how you managed your problem.

Thanks,

Hannes

Hi,

check with 'ps' which process is consuming the memory. If it is an SAP process, open an OSS call, if it is another process, open a call at the company providing this process

Thanks,

Hannes

Without knowing your actual memory parameters it´s impossible to help you.
