Connection to user , terminal lost error in SM21 Q0 4

[santoshsap]

We are having a issue where users in our ECC6.0 systems are having their connections dropped. These systems are located at a remote location

User's are trying to execute VIM related transaction like ICC cockpit & VIM analytics ( /OPT/VIM_ANALYTICS) there is a sudden disconnect .

Updated the SAP GUI level 760 and also upgraded adobe reader to the latest , but still issue persist every time when he execute the VIM transaction.

in SM21 log i see number of entries like

Connection to user 14940 (***), terminal 84 (-7ZG0LH2T) lost

i have taken the trace and validated with user

LGN_SMCLT_LOGON_ERROR< >0120< >Sap Web Dynpro Client cannot be started by calling:<
ENTRY : >LGN_SMCLT_LOGON_ERROR_CODE< >0030< >Error Code:<
ENTRY : >LGN_SMCLT_LOADLIB_ERROR< >0120< >Cannot load Web Dynpro Client library %s.

can you please help me on this

Hi Santosh,

With these many application servers do you have logon load balancing enabled?

Also have you noted particular application servers having the issue all around?

Are the application servers in the same subnet on your network?

And also is your parameterization consistent between them?

Kind Regards,

Johan

Hello,

The messages shared by you are caused mostly due to network issues but since you are saying that network had been good, in that case you may monitor Memory usage as well from ST06 and see if memory shortage appears during the issue.

I faced this problem once where due to such messages in SM21 we used to be misguided towards network however later on, it turned out to be memory issue.

Best regards,

Sujit

Hello Isaias,

The end user is not facing any network issue , i have checked using ping < IP> -t , it is continuously pinging to sap network.

SAP GUI terminates all of sudden when he is doing the work

I have captured the logs from dev_disp :

Hello Jami,

It looks very much a network related issue...

What is logged at the "dev_disp" trace file around the time of the SM21 entry?

And when the end user faces the issue, please ask them to click "yes" or "error details" to see the detailed error message. What does SAP GUI say? Something like "connection reset by peer"?

Regards,

Isaías
