I am running the NCSA httpd server on FreeBSD 1.1.5.1R and handling about 16,000 connections a day. Last night I noticed that the server had started to refuse connections. On logging on I noticed that only one httpd process was running and that the system was virtually idle. I killed and restarted httpd but this did not resolve the problem. I then did a "netstat" command and noticed that there were a lot of tcp connections most of which were in some sort of terminating state. I eventually cleared the problem by rebooting the machine. It occurs to me that my problem may be due to some buffer or array becoming full with all these closing connections. I had a quick grep in the netinet sources but did not spot anything obvious. Is there such a limit which I can increase? If not could anybody advise me how I can get around my problem. -- Jose Marques <jose.marques@las.ox.ac.uk>
