Interesting. So, it's just me then (which is why there haven't been any panic reports from me for a while). There's heavy use of the following modules to the tune of 3*10^9 packets a day peaking at several 1000Mbits/s: Id Refs Address Size Name 1 10 0xffffffff80100000 6f3108 kernel 2 1 0xffffffff80a22000 4986 if_lagg.ko 3 1 0xffffffff80a27000 9f9 pflog.ko 4 1 0xffffffff80a28000 5292 if_bridge.ko 5 1 0xffffffff80a2e000 350f bridgestp.ko I suspect it's blowing up in there somewhere a few times a week. I'll try compiling them into the kernel and see if that yields a useable vmcore. Ian -- Ian Freislich
