Hi everyone!
I have an interesting observation I've been making recently and am
wondering if anyone else has an idea about this. We're running
Intermapper 4.6.4 (build 7A221) on a 1.42GHz G4 mini with 512MB RAM
and running OSX 10.4.11. I've occasionally noticed our map complaining
that our main router was bouncing (down/up) 10 times within a half an
hour and dropping 36% of it's packets, but no one seems to notice a
degradation on the network (everything seems fine, network is
definitely up and running). I can even ping the router (in fact I can
even ping *through* this router to public servers) from this machine
through one of these dropouts and my ping tests don't lose even one
packet. The map continues making this claim until I restart the
machine itself, then the complaints go away and the router looks fine
for roughly another week, when the pattern repeats.
I've taken a look into the Intermapper detailed logs for network
events, but that doesn't reveal many surprises - it's logging the
router going down (usually for 24 or 27 seconds, occasionally 57
seconds) until the reboot, then the problem magically goes away.
Admittedly some of the logs are flashing by so quickly it's hard to
catch them all (it's a busy map:)), but I don't think it's revealing
*why* it's having a problem.
Interesting and revealing is the fact that it doesn't complain about
the routers at remote sites, which all end up going through our main
router to get to our server.
Anyone have any ideas what this could be? I'm starting to doubt that I
have a networking issue that no one has noticed yet and am starting to
think that Intermapper is having some issue it hasn't had before. I
haven't noticed any other symptoms on this machine (nor have I noticed
any issues with the network, which I would since this is our main
router), although it's not a very busy box (Intermapper, secondary DNS
and gathering some performance characteristics from another server are
it's only real functions).
Looking forward to investigating any ideas that come my way ...
