Intermittent network flappage (ACLs)? Maybe a tcpdump would have provided
more insight, than just rebooting the servers...

Hi,
I have been running Hobbit 4.2.1 on Fedora Core 4 for several months
now. Today, in the middle of a normal day when there was supposedly
nothing going on that would have caused this, about 30 servers started
reporting red connectivity, then a few minutes later would switch back to
green, then back to red again - causing very many alerts to go out. There
doesn't seem to be anything similar about the servers that this was
happening to, it was just random. I was able to ping these servers from the
hobbit server, so it didn't seem like there was really a connectivity issue
for hobbit getting to them. I restarted the hobbit service, rebooted the
server, checked the logs (nothing was logged the time it started
happening). I then moved all the logs to a different directory and
restarted the service. After about 1/2 hr things went back to normal. Does
anyone know what might cause this strange behavior and anything to do to
prevent it from happening in the future.
Thanks in advance,
Billie
