SAP Freeze

Dear sir,

I have problem on SAP Production Server.

We sometimes encountered a freeze, ranging from 1-10 minutes in office hour.

When this happens, SAP just freeze, and we have to wait for some times before it is usable again.

It happened again today.

After that I go to tcode SM21 and check the log there.

I found this log, (does it have anything to do with the error?)

Documentation for system log message R4 7 :

The user is deleted after an internal error. The specified error

number has the following meaning:

Delete session 001 after error 050

thxxmode 1384 001050 ThResFr delete
