We have noted another incident
in our testing environment where we have noted that there
is a concurrency issue with the drools and mvel version we are using
where the threads are blocked for a long time resulting the
application node/JVM reach an unexpected state which
needed to be restarted.Could some one look into this if there
is a known defect on this and if it has been resolved in a later version?.
In our case it has happened when we
deserialize the serilized KnowledgeBaseImpl by multiple threads
and it seems that the problem is due to usage of a java.util.WeakHashMap
as a class variable in

Subject:
Drools Community Issue.
Hi Ardash,
I've seen details of the recent issue you
have experienced with the community Drools product; I was keen to contact
you regarding this.
We have been a strategic and global supplier
to HSBC for many years, and have built our success largely on our ability
to provide full enterprise services and productised versions of community
products, that are fit for enterprise use.
In the case of community Drools, our productised
version (JBoss BRMS) provides a full testing, certification, commercial
assurance eco-system, and 24*7 SLA support service - which would appear
to be ideally positioned to help address issues such as that which you
are currently experiencing.
Ardash, given the appetite of HSBC to mitigate
the risk associated with the use of community software alone, I would welcome
the opportunity to have a brief initial conversation with you concerning
the above.
Might there be a suitable number for me to
reach you in the coming days?
Kind regards
Imran
