> There are some random deadlocks occurs with jdbc persistence storage since Sandesha2 core access the table resources in different orders. Although these deadlocks are rear there is a possibility of getting them. 
> As a solution for this problem we can lock the transactions at the storage level and let only one transaction to proceed. Then there is no chance for dead locks.
> This appears to be not a proper solution but it can prevent the deadlock occurrences.
> This may reduce the performance since it prevents parallel processing and is not solving the problem in a distributed environment.
