I've been monitoring lsof all day - the startup has 63 after the switch
connects, it dies at about 93 (probably hitting ulimit for the shell
running the controller). The one crash I was able to capture involved 30
CLOSE_WAIT sockets on different ports to my switch, although I don't have
any log on either side that has recorded an actual switch disconnect. I've
started a tcpdump for the switch connection in an attempt to see what
packets seem to cause this problem.
I'll let you know when/if I get more information.
