Hello, I'm building a pair of firewall with 10.3 and I see some rare segmentation faults (5 in a week) in processes like wc, sh or ifstated. wc, sh are used by some scripts who check the state of the interfaces and the state of bgp sessions. Ifstated called theses scripts too. I thought there was a bug in ifstated so I made a small program in perl to do the same thing but the problem is not in ifstated. The machines are some Dell R730, I've checked the memory with memtest86 for one week without error. The problem occurs on both firewalls so i don't think this is a hardware problem. Any idea? Thanks, regards. ifstated -------- Core was generated by `ifstated'. Program terminated with signal 11, Segmentation fault.
