fix: issues from RPC testing

[aloknerurkar]

Describe your changes

• In some cases the sender was not getting triggered properly causing the txn to be stuck in the DB. Once a new txn comes in the trigger happens, but we need to be more aggresive.
• Added a timeout of 10m for txns. If it takes more than that, we fail the operation.
