Hi Serge,
Thanks for that. I note these revisions on the following branches for
this change:
4.0 - 14113
4.1 - 14117
TRUNK - 14118
Has this patch been tested against a system setup including JMS cache
replication?
Regards
Brett Randall

Subject: Re: Deadlock in Cache
Hi Brett,
I have committed modifications to the cache system so that we don't lock
everything on a cache flush. This will be in the next release of the
4.0.x and 4.1.x versions.
Regards,
Serge Huber.

We have a production site suffering the same intermittent deadlock
issue identified in http://www.jahia.net/jira/browse/JAHIA-639 . This
is a Jahia 4.0.5 system. The result is a completely deadlocked Jahia
engine, no rendering, no authoring.
I'm enquiring whether this bug is likely to receive any attention in
the near future, given the severity.
Stack traces below - I will also update the Jira.
Found one Java-level deadlock:
