[Xymon] flapping DNS error

[Boldt, David]

I have recently downloaded xymon version 4.3.11 to experiment with as a
replacement for the last publicly available version of Big Brother. It is
running on Solaris 10 x86.

The http test on the Display server, for itself, has a flapping status for
http with DNS errors.

I've experimented with the following, restarting the xymon server
application each time

server/etc/tasks.cfg

  CMD xymonnet --report --ping --checkresponse --concurrency=64
  CMD xymonnet --report --ping --checkresponse --no-ares

server/etc/tasks.cfg/hosts.cfg

  130.11.50.48    owipm1.er.usgs.gov      # bbd http://owipm1.er.usgs.gov
=130.11.50.48

I am only monitoring the server itself and one remote host.

xymond.log shows

2013-06-05 00:49:40 Flapping detected for owipm1.er.usgs.gov:cron - 5
changes in 1507 seconds

xymonlaunch.log shows many of these

2013-06-05 10:35:04 Task xymongen terminated by signal 6
2013-06-05 10:36:04 Task xymongen terminated by signal 6
2013-06-05 10:37:06 Task xymongen terminated by signal 6

I've run a script which uses dig on the FQDN for the server once every
second,
and have never seen even a significant delay, let alone a failure.
