Memory Paging dump in ST22

[Former Member]

Hi All,

I am getting MEMORY_NO_MORE_PAGING dump in st22. This is occurring very often, i checked the memory parameter rdisp/PG_MAXFS the value is 65536, please tell me what changes shall i make to get this fixed. If i change the value of rdisp/ROLL_MAXFS will it affect other memory parameters.

Consider setting both "rdisp/PG_MAXFS" and "rdisp/PG_SHM" to the same value.

This usually helps avoid performance issues related to paging memory.

And this would not affect any other parameter.

Hi,

Please go through below sap note

1563748 - MEMORY_NO_MORE_PAGING dump occurs

133909 - Maximum value for PG_MAXFS, PG_SHM, ROLL_MAXFS, ROLL_SHM

Also provide more information about SAP system, OS?

You can monitor SM04-->Goto-->Memory (Page Column) to see which user/what tcode, program is consuming more page memory.

Hi Prithviraj,

OS- Windows server 2008 ( Std edition)

Application- SAP ECC 6.0 EHP 5

DB - Mssql server 2008

As per the note 133909, max value for rdisp/PG_MAXFS can be 250000, can i set the value to 128000( RAM 32 GB), along with this parameter do i need to change any other parameter value.

Hi,

As per parameter is concerned it is not a problem if it is set to too large a size.

But I would suggest you instead of going to the max value try with 100000-150000.

If that helps you in overcoming the issue else increase it again, provided you have enough space at File system level.

Prithviraj.

Hi Aditya

the error means that there is an overflow in the SAP paging area. You get some more information about this in note 133909. You just should increase the profile parameter rdisp/PG_MAXFS.
