When running a poller discovery from the central web interface it errors out.
Error message from the web interface is: "ERROR : Connection lost with the poller agent"
I have 2 networks that I try to scan. 1 the discovery daemon on the poller will die. The other one it seems to live, but still produces the error. The error message below are from the scan that doesn't kill the daemon. If I limit the scan range, it seems to finish, i.e. using /28 instead of /24. Not sure if it matters but the Central is on the Internet in a data center. The poller in within a lan on a private network and I have port forwarding to the poller.
