Not enough quota is available to process this command

Question

We have a .net application, which supports MS Sql server and Oracle data base.

Architecture: Application architecture is this we are using a WCF service for Business logic and data base operations. WPF/Windows form front end.

Operations: In our application we are doing excessive use of data base. Thousands of calls for database from wcf service along with some engineering calculation/allocations inside code.

Problem: So while we are using application with wsHttpBindings application is not giving any error but performance is very low, while we are using netTcpBinding application performance is good but randomly we are facing this Not enough quota is available to process this command and application crashes. User has to start application again and start working, which is very costly because we are doing a lot of calculation/allocations and engineering operations. Some time we are losing calculation/allocation process as well.
