You could edit the source code to change 50 to a smaller number and try again. To ensure that your test is not influenced by previously cached entries, delete /opt/local/var/macports/pingtimes before trying again. If you didn't see this problem with other ports that are not perl modules, then presumably there is some smaller number of simultaneous pings that will work. But it also sounds like it may be a bug in the Carbon Black software you mentioned using.
