Local fix
Problem summary
A huge amount of blocked threads on com/ibm/bpe/message/DeployedSDOMessageTypeHelper are observed which all call the computeType(DeployedSDOMessageType) method. As this method is synchronized the call stack is increasing quickly causing delays in the processing. PRODUCTS AFFECTED IBM Business Automation Workflow
Problem conclusion
A fix is available which changes the synchronization behavior of the computeType(DeployedSDOMessageType) method to avoid these lock situations.
Temporary fix
