Hi Srini,
You can find the KBA 1524031 at this link:
http://service.sap.com/sap/support/notes/1524031
It helps you to check if the patch level is consistent in your system (SAP_AP and IPC).
If the patch level is correct, you may try to reactivate some objects as described in note
1635670 (Runtime object for VMC table is invalid). Reactivating the VMC tables often resolves this issue.
Regards,
Timea
