Trevor,

The related issue was fixed in Drools 5. 
Which Drools version is used in the SOA 4.3 IR1 release?

I backported JBRULES-1876 into the SOA branch bellow:

https://svn.jboss.org/repos/labs/labs/jbossrules/branches/Branch_4_0_2_SOA_4_2

Please advise if you have any problems.
Comment 6 Julian Coleman 2009-06-09 09:20:59 UTC 
We will release the new JBoss Rules version with SOA 4.3.0 CP02.
I will merge the Drools 4 changes into new SOA tags for SOA 4.3 (and SOA 4.2).

Comment 10 Dana Mison 2009-07-29 03:00:47 UTC 
added to 4.3.CP02 release notes as resolved:

JBRULES-1876 - The RuleAgent can now safely refresh its associated RuleBase whilst a new stateful session is being created on the RuleBase by another thread. Previously this could result in a deadlock.
Comment 11 Tihomir Surdilovic 2009-09-10 18:22:29 UTC 
closing issue as fixed.
