Parameter - em/stat_log_timeout

About Parameter

In SAP Memory Management, the sizes of user contexts are

user contexts are collected for statistics purposes.

This parameter specifies the interval at which the sizes are

written to a file.

SAP Note 1156368 -

em/stat_log_timeout cannot be changed dynamically

I think this information will help you

The file memflush records the sizes of user contexts.

The purpose is to be able to recognize and analyze problems in connection with large user contexts.

memflush contains a current image of the user contexts.

The refresh interval is em/stat_log_timeout in seconds and em/stat_log_size_MB records a history of the user contexts whose size exceeds the threshold value in MB.

To avoid impairing the performance, the parameters must be set so that user contexts with normal size are not recorded.

Default:

em/stat_log_timeout = 600 ;update every 10 minutes

em/stat_log_size_MB = 20 ;Recording for more than 20 MB

Well - you could easily check that by doing the following:

- http://service.sap.com/notes

- enter "em/stat_log_timeout" as search term

You can also start transaction RZ11, enter the parameter and read the description. Basically it's used to "flush" dirty memory pages onto disk.
