Karthick Sankarachary commented on ODE-576:
-------------------------------------------

Ciaran,

The root cause of this issue probably stems from the process cleanup code. It 
seems that it does not release in-memory process DAO objects when they are 
undeployed or redeployed. I have put together a patch (called 
process-dao-cleanup.patch) that attempts to clean up such objects properly. Can 
you please check it out at your convenience? If it works, I'd rather leave the 
process hydration code alone.
