Software running under VMWare receiving TCP/IP Errors
Posted on 2013-01-16
Wondering if this sounds familer to anyone.
Have a client that is moving to a new hosted server setup at Infinitelyvirtual.com
I don't know what the host hardware or OS is. Guest OS is Windows 2008 Server R2.
They are currently using Gentran 5.3, which is 64 bit compliant.
Gentran is installed on one VM (a "app" server) and is talking to SQL Server (2008 R2) on another VM. The other VM runs nothing but SQL Server.
Gentran is reporting a low level error:
ODBC: MFC database exception in Program/RETCODE: Server/-1State:08S01,Native:11,Origin:[Microsoft][ODBC SQL Server Driver][TCP/IP Sockets]
State:01000,Native:10054,Origin:[Microsoft][ODBC SQL Server Driver][TCP/IP Sockets]
General network error. Check your network documentation.
which basically says there's a network problem.
Checking the VMWare forums, others have had this issue as well (not Gentran specifically, but with apps in general talking to a SQL Server).
We've done quite a bit of troubleshooting on this already, and have gotten no where. Most of the VMWare forum threads talk about enabling/disabling various TCPIP settings.
We've already tried RSS, Chimney Offload, and NET DMA changes on the adapter/OS and nothing's made a difference.
We do have this same version of Gentran running on a physical server and have no issues with it, so it seems related to the VM environment somehow.
I'm going to stop here as I'm not sure what other information to provide.
