how to resolve SWAP usage problems

[former_member612721]

Hello SAP Community,

We have a problem regarding swap space on one of our SAP ABAP systems

It is using too much of swap space

This linux server hosts 2 SAP ABAP systems, one of which is using significantly more swap space

cat /etc/SuSE-release
SUSE Linux Enterprise Server 11 (x86_64)
VERSION = 11
PATCHLEVEL = 4

Does restarting the system help - And how can we avoid this issue happening in the future?

Thanks in advance

Hello Alexandru,

Restarting SAP might help, depending on its memory parameterization. But the issue would come back over time.

I believe that you would have two options to tackle the high swap usage issue:

1. Add more memory (RAM) to the server/VM; or
   
2. Tune the SAP memory parameters (reducing the memory usage), so each SAP system does not use too much memory, avoiding the need to use swap space. This might lead to other issues, though, depending on your requirements for each SAP system.

Regards,
