Here's a new one I just looked into. Every time I try to trash more
than one mail item at a time (select a bunch of mails in TBird and hit
'Delete') I get a failure. The logs have a huge dump which I can attach
if necessary. But the key lines are:
Caused by: <openjpa-3.0.0-r422266:1833209 fatal store error>
org.apache.openjpa.persistence.RollbackException: Optimistic locking
errors were detected when flushing to the data store. The following
objects may have been concurrently modified in another transaction:
[org.apache.james.mailbox.jpa.mail.model.JPAUserFlag-1530940342]
Caused by: <openjpa-3.0.0-r422266:1833209 nonfatal store error>
org.apache.openjpa.persistence.OptimisticLockException: An optimistic
lock violation was detected when flushing object instance
"org.apache.james.mailbox.jpa.mail.model.JPAUserFlag-1530940342" to the
data store. This indicates that the object was concurrently modified in
another transaction.
I understand locking, etc. I googled 'optimistic lock' but I'd have to
dig deeper to understand how it's used in JPA. In any case, apparently
these locks are fighting with each other when more than one update is
attempted on a mailbox.
This is very reproducible. So far, I have never been able to delete
more than one item at a time.
I guess my current version is in the ballpark of 3.4+. It was a clone
of the master branch right after 3.4 went live.
Give me some pointers, and I'll do a little debug and analysis. But at
this point, no idea where to start. Suggestions?
