Hi Rama Krishna,
Can you please confirm the HANA version you are currently working on?
If you are on SPS11 but lower than the revision 111 then the issue is caused by a known issue addressed in Revision 111 with the recovery of the xsexecagent
Please refer the below link for a similar issue and the SAP note for Revision 111
