> We noticed that this fix is causing congestion. Queue operation were talking longer time than expected.
> There are two lock being used for queuing commands, which is causing delay.
> First, all queue command function of CallableQueueService is synchronized.
> Second, add function of PriorityDelayQueue need to acquire ReentrantLock
> lock, which was added as part of this patch.
> Acquiring two lock for queueing a single command was slowing down the system.
> Server was taking more than 4 sec, just to queue a command.
> After we rollback this patch and server was back to normal.
