Hi Surender,
Is it a general user issue or are you the only user facing that issue ? Does the error occur right after you enter user/password ?
From the GUI session status bar, I see " Memory Low. leave the transaction before taking a break".
This looks like a improper memory configured system. I would suggest that you review your memory parameters as per the SAP note 146289.
If you already have the memory parameters set to at least the values suggested by that note, please further increase the parameters below:
abap/heap_area_total
abap/heap_area_dia
Hope that helps.
Kind regards,
Eric
