Hello Ankit,
Take a look of this note that mentioned problems with problems in table: RSCOMPTLOGO.
1708904 - Process chains are structured incorrectly in BPC753
In the SAP support portal there are lot of SAP notes with problems in RSPC, most of them related to BI, but maybe you can find the solution in those notes.
You can also try to delete old logs using: RSPC_LOG_DELETE
Kind Regards,
Mariano
