We have a recurring problem where we cannot get reverse name lookup on one particular domain. We can reverse anyone else we've tried and others can get reverse name lookups from them. It wouldn't be such a big deal except this domain is one of the biggest ISPs in the area and lots of visitors come from there. When this problem kicks in, folks dialing in on their lines get huge wait times while the reverse service times out. This same problem affects nslookup, ftp, telnet, etc, so its not a webserver-specific thing. The puzzling part is the intermittancy, it works fine for days, then dies for anything from a few minutes to several hours. Rebooting does not clear the problem. This problem's appearance seemed to coincide with the upgrade to 2.1.5, along with the inability for certain other formerly working programs to fork. Any ideas at all? The other guys are running BSDI and are willing to work with us, if we can give them a line of investigation. Cliff
