YES! I have been having problems with NetLibSelect as well. I posted a
problem on Friday where NetLibSelect works for a while and then stops
reporting that there is data available in the socket. The system events
keep working. We have done some troubleshooting and this is what we have
found:
1. the socket does not get closed, i.e. it is still valid/available
2. the event loop is still running, it responds to taps but unlike yours we
never get the FDIsSet on the socket
3. we tried enabling tracing in the NetLib and using NetLibMaster to
retreive and dump the logs and it looks like at some point the
socket/network stack just stops telling us there is data. We see on the
function trace the app going into and out of NetLibSelect over and over and
over ...........
4. if we close the app which closes the socket and try to reconnect the call
to connect fails ( not the call to socket )
It is sounding there there is a possbile bug in the NetLib stack.
