Problem with labview build shared libray that uses tcp/ip

Situation:

We have build an LV dll, that uses tcp/ip to connect to a remote LV application, this is done using TCP/IP.

The dll works fine and is integrated into a suplliers SW (C#)

 

When this C# applications starts up a RTX extension and communication to another PC, also via TCP/IP but not via LV dll)

Then the problems begin, high CPU loads and thus laging the computer.

Investigation in taskmanager show that at that point the dll and system proces us all the available CPU power, even if no functions are called in the dll. (just loaded)

Before starting the RTX extension it uses 0%.

 

It looks to me that the LV runtime environment is somehow interfering with the RTX extension.

 

 

Anybody had such problems, suggestions on how to further debug or solve it?

 

Thanks,

 

Ben Engelen
