Only way to recover is power off. No panic dumps or any indicators in logs. Looks like a spin lock. In our particular instance it occurs at aproximately 1 week intervals. This problem has been present in all 6.X releases. Using GIANT-LOCK on the network stack stops it (apparently) from happening. Although under previous 6.X releases system would still occasionaly panic (have not analysed the cause; may be another reason) >How-To-Repeat: Unknown exactly. We are running the latest asterisk12 port with phones on an inside lan (192.168.X.X) bge1 and asterisk accepting SIP calls from a public IP behind a Cisco PIX on bge0. Just reinstalled from CD to FreeBSD 6.2-RELEASE #0 and locked after 4 days. >Fix: Somewhat of a work around is to configure the system for GIANT-LOCKing on the network stack. >Release-Note: >Audit-Trail: >Unformatted:
