    dns resolution


      Is there anyway of troubleshooting dns resolution?  As it stands it appears to be speratic.


      Here is the license information:

      Module Name

      User Device Tracker
      Service PackNone
      Allowed number of monitored ports25000
      Current number of monitored ports17961


      I have only implemented this in the last couple of days, so its very new.

          It appears that only 1026 ips have been resolved of over 4110.

            After some further investigation I found a whole heap of the following segfaults in the UDT.BusinessLayer log.  The exact cause is unknown and it doesnt happen to every node every time and some more often than others.

            I have a ticket open for this now, I was just wondering if anyone has experienced similar issues.
