Re: [hobbit] Antwort: [hobbit] Antwort: Re: [hobbit] ping test is too slow

[Jerald Sheets <questy (at) gmail.com>]

I am running RHEL5.2, but am not having anywhere near the latency you are.

The only apparent difference between our output is that I am on Xymon
4.3.0-0.beta2.  I am also going over a gigabit network, but my DNS
resolution time never crawls above the microseconds all that much.  Your OP
states that sometimes it takes up to 20 seconds to get resolution, and I'm
wondering if that isn't where you need to concentrate your efforts?

As much as I hate to suggest such a thing because of other potential bugs,
could you gain any benefit from having nscd running on the Xymon host only?
