Hi guys, I'm going to take another stab at getting some help. For the last 6 months my FBSD gateway has been locking up every few days, usually about once a week. No panic, no reboots, just a hard lock with no response on the console or over the net. I've replaced literally every piece of hardware with the exception of the case and power supply. No change. I've upgraded from 5.3- to 6.0- to 6.1-STABLE. No change. I've researched as much as I know how and still come up with hardly anything. I have turned on BREAK_TO_DEBUGGER, WITNESS and INVARIANTS and the only indication I've gotten is a lock order reversal that's *similar* to http://sources.zabbadoz.net/freebsd/lor/017.html. The line numbers in pf.c don't match up with LOR 017, but that's about all I can tell. I'm reasonably certain the issue is with pf, since I have 3 other non-gateway servers humming along with no problems. The hardware is nearly identical - their RAID cards are different, but I've tried running my gateway on just a single SCSI drive and had the same lockup issue. Of course, the issue could be somewhere else, but I'm at a loss as to how to find it. I'm running my console over serial so I can log anything that's necessary. I've been able to break to the debugger, but to be honest, I don't know what to look for. I've seen several posts on the lists about posting the output of debug commands, but I figured it to be in poor taste to just dump my output here before someone asked. I'm getting a lot of heat from the boss since our VoIP phones don't work when the gateway locks up. If someone can help identify and/or eliminate this issue, I'm more than happy to do everything I can to provide the necessary information. Thanks.
