Subject: another wireless crash
Date: Fri, 04 Nov 2011 14:00:51 -0700 [thread overview]
Message-ID: <4EB45283.2090802@candelatech.com> (raw)
This is what killed my system while I was away from the serial console.
I had around 135 virtual stations running, and they were idle so being
periodically disconnected from the AP for idle-ness.
This is mostly FYI. I'll re-build with debugging and do some more
testing to try to track these down.
