Deadlock in Cache

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:

=============================

"TP-Processor70593":

  waiting to lock monitor 0x080cc0bc (object 0x92ffe878, a
org.jahia.services.cache.Cache),

  which is held by "TP-Processor70118"

"TP-Processor70118":

  waiting to lock monitor 0x080cc0f4 (object 0x92ffe8a8, a
org.jahia.services.cache.Cache),

  which is held by "TP-Processor70593"
