Dave, Is your router showing as down or maybe in alarm mode? I have a similar issue with many end nodes sporadically going into alarm mode due to packet loss but when I check into it I can't find anything wrong and everything is working fine. I have come to the best guess conclusion that it's probably the NIC card on the PC I have Intermapper running on. If the NIC card is losing packets then it will probably show as a mis-reading on the map. Now I could be totally wrong but because of this I have decided to move Intermapper to an empty blade server I have along with all my other tools. I had to find an excuse to fill it up with something anyway...

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 ...
