I would assume (without looking at your code) that this is equivalent to 
the Windows error "WSAEWOULDBLOCK" (10035) for which Microsoft's docs 
say this:

Resource temporarily unavailable.
     This error is returned from operations on nonblocking sockets that 
cannot be completed immediately, for example recv when no data is queued 
to be read from the socket. It is a nonfatal error, and the operation 
should be retried later. It is normal for WSAEWOULDBLOCK to be reported 
as the result from calling connect on a nonblocking SOCK_STREAM socket, 
since some time must elapse for the connection to be established.


Does that help?  If not, at least provide information about what 
platform you're running on, and preferably post the code, if you can 
reduce it to only a few lines which still reproduces the problem.  Many 
people don't like to spend time downloading code from who knows where 
and attempting to run it on their own machine, but could find the 
problem with a quick inspection of your code if posted here (but not if 
it's hundreds of lines!).
