PDP daemon crashes with core dump files after upgrading to R77
Symptoms
  • PDP daemon crashes with core dump files after upgrading to R77.

  • Deleting all entries from the PDP kernel table and the PEP kernel table on Security Gateway resolves the issue for some time:
    [Expert@HostName]# fw tab -t pdp_super_sessions -x -y 
    [Expert@HostName]# fw tab -t pdp_ip -x -y 
    
  • PDP core dump files contain the following stack:
