Hi Tim,
This looks similar to, but is not the same as XORP bug 383. I would suggest
opening a new bug in Bugzilla so that the XORP team can investigate.
If these are the only routers running OSPF on this network, then there might
be some sort of race condition related to DR election. This might explain
why it happens when you enable all four at the same time rather than one at
a time. I only have 2 routers running XORP here, but I'll see if I can
reproduce the issue.

Subject: [Bulk] [Xorp-hackers] OSPF Failures
I've been having ongoing OSPF death problems with my simple fully meshed
four router test bed.
If I bring all four routers up at the same time, OSPF quickly dies. If I
bring them up one at a time, sometimes they will stay up and stable.
The event is:

I've attached all four router configs in case it helps.
Any ideas?
