SG105 lockup / crash

jamesharper

My SG105 with 17.0 Beta 2 on it just became completely unresponsive. No icmp or arp. I connected a serial console and nothing responded, indicating that there was a kernel crash in play. I didn't have a screen I could connect so I couldn't be sure.

In my experience sometimes Linux will log some kernel messages leading up to a crash. If this is the case, what logfile might I look in for this?

If it happens again I will look into hooking up a serial cable to a server to catch anything that happens.

Thanks

James

    the crash happened sometime after 18:15, and I powered cycled it around 19:00. No indication of a problem beforehand.

    I guess i'll just have to see if it happens again!
