Socket Exception - Connection Reset

Hi,

I am pretty new to SOAPUI.

There are couple of failures (Socket Exception-Connection reset) that I am observing while using SOAPUI 3.6.1 free version for REST APIs. Usage is through the GUI provided.

1. Intermittent failures at the start of execution of REST APIs.
The first time the test suite will fail and if you run it the next time, it works fine.

2. The test scenario is that after a particular test step I have to wait for 15 minutes before executing the next test step. I have used the delay function in SOAPUI for waiting. After the execution of the delay test step, it throwing the Socket Exception-Connection reset. Socket Timeout in preferences is empty.

Any help on this is highly appreciated.

Thanks,
Antony
