Yesterday there were 91 "5xx" errors reported generated by Cosmo 0.7.1
on the Hub:
I actually find 94 errors in the log (can't explain the extra 3 right
now). 46 of those were straight "500" errors. The rest are 501.
15 errors are PROPFINDs (501s); 7 of those are PROPFINDs on the /
resource. 2 are against a /mc URL (same collection and user); the rest
against a ticketed /pim URL (anonymous auth).
33 errors are 501s against /cmp/signup. My best interpretation is there
was 1 user (based on IP) who tried 19 times to sign up with Opera 9.23.
Another user (different IP) tried 5 times to sign up with Opera 9.10.
A third user tried 9 times with Opera 9.23. All users were on Windows.
39 errors are 500s against /mc/collection. There are 2 authenticated
users and one ticket. The ticket is 0.7.1.dev-r15338, 1 auth is 0.7.0.1
PPC, the last 0.7.0.1 intel mac.
Searching for ERROR in the Cosmo logs, I see 4 "[DeadlockRetryFilter]
the server encountered an unexpected error", with following 2 lines:
org.hibernate.validator.InvalidStateException: validation failed for:
Maybe not a 500, but right before one, I see a WARN:
2007-09-19 09:36:55,039 WARN [EventExceptionValidator] event validation
net.fortuna.ical4j.model.ValidationException: Property [DESCRIPTION]
must be specified once
with the event:
2007-09-19 09:36:55,040 WARN [EventExceptionValidator] error validating

There's no other indications of errors I can see.
I don't pretend this email is well-organized or sufficient for next
steps or anything like that. These types of analysis are time-consuming
so I'm just stopping at an arbitrary point on this first analysis so
people know roughly what's up and the info currently available.
The info from the Cosmo logs is probably all there is. Additional data
gathering probably requires painful network tracing to see the actual
messages returned over the wire in the 500 response body.
My guess is that we consider some of the above actionable, even possibly
short-list. Recommendations/analysis abound, but I'll start with just
getting this initial report out there for people to mull over.
