Hi,
We are running CAS 5.1.2 with Mongodb for ticketing and ldap for authentication
and have been seeing the following error every so often during heavy load test
which seems to give 500:Internal Server Error and a
ConcurrentModificationException in the logs. We have not done any changes to
the login webflow so we were wondering if anybody has encountered something
similar.
