Every few hours or days the system stops responding or locks up. This is a system that had been running without problems before I upgraded it from a year old 8.0-STABLE a week ago. Most times when it locks up it still responds to pings. Some times I can still SSH to it, but otherwise I have to get on via console and reboot it. Almost all traffic destined to it or originated from it travels through an if_bridge(4) interface. Today I was able to use top to see the state of processes that are hanging: > 70232 root 1 116 20 5668K 3232K *lle 0:00 0.00% snmpget > 70235 root 1 116 20 5668K 3232K *if_af 0:00 0.00% snmpget > 70244 root 1 116 20 5668K 3220K *if_af 0:00 0.00% snmpget > 70245 root 1 116 20 5668K 3220K *if_af 0:00 0.00% snmpget > 70254 root 1 116 20 5668K 3220K *if_af 0:00 0.00% snmpget > 70306 root 1 96 0 3416K 1112K *if_af 0:00 0.00% ifconfig > 70296 root 1 96 0 3392K 1132K *if_af 0:00 0.00% ping The ping and ifconfig processes were started by me and couldn't be backgrounded or interrupted while in the above state. Today it's as if only one of the bridge interfaces had "crashed" since traffic through the other bridge interface was behaving fine. Really need to get to the bottom of this. Help? Thanks, Aragon
