Here's the original post <------------------------ Hi all, I'm having a problem with CERN http on my web server. Every so often I check the swap use and find that it's too high, about 40% when 15-30% is normal for 15-20 proxy web clients. ps reveals that there are old httpd's hanging about with info like 166 ?? I 1:41:02 /usr/local/libexec/httpd -r /usr.... 2604 ?? IWN 0:00.10 /usr/local/libexec/httpd -r /usr.... 2880 ?? IWN 0:00.11 /usr/local/libexec/httpd -r /usr.... 2901 ?? IWN 0:00.12 /usr/local/libexec/httpd -r /usr.... 12340 p1 R+ 0:00.04 ps -ax When I kill off the first httpd the rest also go, and the swap comes back to normal. When I say first I mean 2604, not 166 which is started by rc.local Does anyone know why this happens, and if I can fix it. Is there any danger of the system running out of memory from these hanging about, particularly if I go away for a month? Eeek! I've just run out of swap. Freebsd does a nice job of killing processes when it runs out, but not the ones that are causing the problem, just the ones that are asking for memory. <---------------------------------- I know of a site using sparcs which has the same problem. They use a cron job to kill all httpd's & restart it. Cheers, Peter Peter Stubbs, St Aidan's AGS. ph +61-07-3379-9911, fax +61-07-3379-9432
