sometimes slow startup extreme switch due to a restart of the OSPF process
During boot sequence: Core was generated by `./ospf'. Program terminated with signal 6, Aborted.
This process crash occurs during clean up of the module. EPM killed processes in some order. RTMGR was gone in the restart. But in ospf it was catching up to reregister with RTMGR. But because RTMGR does not responded, so ospf was stuck.
