Assertion failure: (fds.size() >= FD_SETSIZE)

Hi,

when receiving packets to a ROUTER socket from more than 64 clients I get the attached error. . From a cursory search on the net the problem appears to be the windows limit of 64 file descriptors per pollset. I believe this is configured in the undelying zmq library that gets used by the labVIEW wrapper. Is it possible for you to reconfigure this to a bigger number with the next distibution of the labview zmq library?

Hi,
Do you have a suggestion of what a better size would be? I can see there might be problems making it too large by default. I could try 256, for example.

Hi!

I was looking around for what an appropriate value is supposed to be and from below two links it appears that 1024 or more.

I had a quick go at rebuilding the DLL with a 1024 limit, but since I don't have a test case, I can't verify whether it worked or not. Please try the attached DLLs and let me know if it resolves the issue.
