When the OSPF database is cleared via cli, the LSDB-related information will be deleted and set to null. The crash occurs when RLFA tries to access the LSDB info that was previously cleared and is no longer available. Check out PR1958559 for more details.

Verify if the RE's [on which the RPD core is seen] OSPF database is in sync with the other RE via:

show ospf neighbour detail

show ospf interface detail

show ospf database summary

show database-replication summary

Fix:

Upgrade the node to the fixed release 

Workaround - disable RLFA
