First, it looks like one or more of your daemons was connecting and disconnecting \
repeatedly.
Second, it looks like you tripped the infinite-EVS state bug that we tried to work \
around. We still aren't sure what causes this and most times simply restarting the \
protocol seems to fix it, which is the work around.
The state at the end looks like a bug. It has the ARU as 167 but the highest seq as \
135. Then in the next membership it does establish it tries to issue packet #136, \
but that is lower than the ARU, so that packet id already exists. I'm not 100% sure \
on this because during memberships the token fields can mean different things than \
during regular operation.
The infinite-EVS bug and this exit might be related or caused by the same logic \
issue.
Cheers!

Hello,
We're using spread 4.0.0 on 64-bit CentOS 4 (Linux).
The other day a daemon crashed. Below is what was logged just prior
to the crash. I was wondering if anyone could help shed some light
on this?
Thanks,
Matt
