Also, I noticed that spread apparently crashed on Monday, September
18.  Just immediately before the crash, all the logs on one segment
look like this:

Membership id is ( -1062683843, 1190126481)

[Tue 18 Sep 2007 14:41:20] Configuration at box11 is:

And on the other segment, they all look like this:

Membership id is ( -1062683843, 1190126481)

It looks like the member ship got screwed up somehow, almost as if
the network was suddenly partitioned or something.

Any ideas?

Thanks again,
