Calling RFC's using SAP .NET connector

222 Views

Hello,

We have a .NET project that calls RFC's using the SAP .NET connector. Initially it looked like it works fast and reliably, but when we got to more extensive multi-user load testing we get the following problem:

If 2 users are connecting together, after about 15 refreshes of the web page that calls the rfc, the IIS hangs. If we debug we see the following exception:

<i>CPIC-CALL: 'CMRCV' LOCATION CPIC (TCP/IP) on local host ERROR internal error TIME Mon Jan 03 14:32:33 2005 RELEASE 620 COMPONENT NI (network interface) VERSION 36 RC -1 MODULE ninti.c LINE 1094 DETAIL NiPRead SYSTEM CALL recv ERRNO 10038 ERRNO TEXT WSAENOTSOCK: Socket operation on non-socket COUNTER 30</i>

Any ideas as to what my be causing this?

Thanks,

Yoni
