only on one side. Also check if there is any error message printed for IPC_PROC_ERR.

Recommended Action It is possible to get this message if some protocol packet gets dropped but the
system should recover and move back to FULL state. Do 'show fspf interface' to check the state of
the interface. If it is stuck in state other than FULL provide output of 'debug fspf event' and 'debug
fspf fc pkt ' for the interfaces involved.
