We have been having a problem for the last 24-36 hours on our network. We have about 350 servers (50% FreeBSD, 50% NT/2000 and a few Linux) Servers have started to be inaccessible through our router (and sometimes through other servers). The ARP table in our router will show an INCOMPLETE next to the Arp entry which is having trouble. These problems surface about every 30 minutes and servers will go down about every 4 hours. This problem seems to affect ONLY FreeBSD servers (and 2 Cobalt/Linux servers). In total, about 20-30 servers. Does anyone have any ideas on what we can check? While our network is largely flat, we do route blocks of addresses directly to servers, our arp table in our router is fairly small (about 500 entries). Any help would be greatly appreciated. We have tried a lot, but cannot figure out what is causing the problem. We did not have this problem before, and many of the servers affected have been running for 1-2 years without any problems. We use 3COM and Intel NIC's, Nortel switches (303, 310) and a 7206VXR routers.
