I have a RELENG_5 box on my desk. Unless I run the tcpdump program, it responds progressively slower on the network. This seemed like the most appropriate list to post this question too. This morning, for instance, it had a 9 second ping response time from a machine on the same network segment as it when I came into work. As soon as I typed 'tcpdump' on the freebsd box the ping time dropped to nearly instantaneous. I killed tcpdump and let it run for a while. About a thousand seconds later it suddenly jumped to 1 second, then to 2 seconds. As soon as I ran tcpdump again it dropped back to normal. The uname ids it as 5.3-STABLE #14: Wed Oct 20 10:23:11 UTC 2004, with a GENERIC kernel. I did a new cvsup (along with a tcpdump because otherwise cvsup fails) this morning and nothing new came across. -- William Colburn, "Sysprog" <wcolburn@nmt.edu> Computer Center, New Mexico Institute of Mining and Technology http://www.nmt.edu/tcc/ http://www.nmt.edu/~wcolburn
