During system bootup, system coredump is observed when many DHCP packets arrive before system is fully ready and many flow entry creation failures are observed
System crash and coredump.
-- BIG-IP DHCP proxy is in forwarding mode. -- DHCP relay agent in front of BIG-IP modifies giaddr field of DHCP packets to its own IP address. -- DHCP packets arrive during system bootup and before system is fully ready (i.e., some VLANs, interfaces and routes are not fully up).
Make sure system has come up completely before sending DHCP packets to the system.
Coredump no longer occurs under these conditions.
