Someone just reported that the wiki was down and I thought xen7 might
have crashed again. when I tried to ssh to it my connection timed out.
ping xen7 was fine. I serial consoled in and then immediately tried
to ssh to xen7 again. it worked. uptime showed that xen7 has been up
since this morning and the app servers are all running, etc. There are
no iscsi errors in /var/log/messages.
Is there a possibility that we're experiencing some sort of networking
issue with xen7? Maybe that issue is exacerbating the iscsi bug that
causes our xen hosts to crash?
