Hi all,
Ive done some more testing on this, and whats happening is that a network
disconnection causes the TCP communications between Radiator and the SQL server
to time out (eventually). The time it takes to timeout depends on the TCP
implementation, but it can be a several minutes.
I am looking for a way to improve this, but its very much under the control of
the kernel, rather than Radiator.
I know thats not very helpful, but we are trying to find a solution.
Cheers.
