[Dxspider-support] Spider continues to freeze and/or restart on its own

[Mike McCarthy, W1NR]

There is an issue with the Perl libraries that will cause a hang of 
about 2 minutes or more if you have a crontask that is trying to connect 
to a node that is not responding. It usually times out and continues but 
some users will time out their connections and reconnect. I have not 
seen this issue cause a restart.
