That certainly improves uptime. I believe it is leaking descriptors. It can't possible use so many with the kind of traffic (~7 req/s) it's receiving. I restarted it yesterday with 128K descriptors. # ps -AF | grep varn root 4726 1 0 21419 928 2 Dec09 ? 00:00:00 varnishd -a *:80 -f frontdoor.vcl -p obj_workspace 4096 -s malloc,100M -p thread_pools 4 nobody 4727 4726 0 140497 153232 3 Dec09 ? 00:06:48 varnishd -a *:80 -f frontdoor.vcl -p obj_workspace 4096 -s malloc,100M -p thread_pools 4 # ls -l /proc/4727/fd | wc -l 1253 It's currently using 1253 descriptors. # ls -lat /proc/4727/fd | grep "socket" | head -n 1 lrwx------ 1 nobody nobody 64 Dec 10 11:40 1244 -> socket:[17728046] # ls -lat /proc/4727/fd | grep "socket" | tail -n 5 lrwx------ 1 nobody nobody 64 Dec 9 15:27 23 -> socket:[16402456] lrwx------ 1 nobody nobody 64 Dec 9 15:27 24 -> socket:[16261656] lrwx------ 1 nobody nobody 64 Dec 9 15:27 25 -> socket:[16411051] lrwx------ 1 nobody nobody 64 Dec 9 15:27 4 -> socket:[16216281] lrwx------ 1 nobody nobody 64 Dec 9 15:27 5 -> socket:[16216282] # ls -lat /proc/4727/fd | grep "15:" | wc -l 76 It has 76 sockets that are 20 hours old.
