[Building Sakai] Msgcntr StaleObjectStateException

[Kevin Takacs]

Hi Everyone,

A few of our clients on 2.8 have had the stack trace below appear in
catalina.out.  We were able to sporadically reproduce it in a dev
environment by creating topics and clicking the post button repeatedly with
two users in different sites at the same time.

I did some digging and found this Jira,
https://jira.sakaiproject.org/browse/MSGCNTR-359, however we have already
incorporated the fixes from this ticket and still receive the error.

ERROR TP-Processor56 org.hibernate.event.def.AbstractFlushingEventListener
- Could not synchronize database state with session
org.hibernate.StaleObjectStateException: Row was updated or deleted by
another transaction (or unsaved-value mapping was incorrect):
