Hey Guys, I'm running Varnish 2.0.6 in a production linux server with the following parameters:
varnishd -P /var/run/varnishd.pid -a 0.0.0.0:2000 -T 127.0.0.1:6082 -w 200,2000 -s malloc,14G -p lru_interval=5 -f /etc/varnish/varnish.vcl The server has a total of 17G of RAM and no swap at all. When the cache reached its limit of 14G, varnish started nuking objects and everything looked good. However, it sill continues to allocate more and more memory without releasing it. Memory usage growth is very slow though. Also the committed memory is like 24.2G now and keeps growing steady. Is that normal? Here's the output of varnishstat -1: uptime 416905 . Child uptime client_conn 1445639 3.47 Client connections accepted client_drop 0 0.00 Connection dropped, no sess client_req 10977250 26.33 Client requests received cache_hit 8316582 19.95 Cache hits cache_hitpass 2 0.00 Cache hits for pass cache_miss 2660450 6.38 Cache misses backend_conn 15761 0.04 Backend conn. success backend_unhealthy 0 0.00 Backend conn. not attempted backend_busy 0 0.00 Backend conn. too many backend_fail 3990792 9.57 Backend conn. failures backend_reuse 2644716 6.34 Backend conn. reuses backend_toolate 15693 0.04 Backend conn. was closed backend_recycle 2660401 6.38 Backend conn. recycles backend_unused 0 0.00 Backend conn. unused fetch_head 0 0.00 Fetch head fetch_length 2659445 6.38 Fetch with Length fetch_chunked 0 0.00 Fetch chunked fetch_eof 0 0.00 Fetch EOF fetch_bad 0 0.00 Fetch had bad headers fetch_close 0 0.00 Fetch wanted close fetch_oldhttp 0 0.00 Fetch pre HTTP/1.1 closed fetch_zero 0 0.00 Fetch zero len fetch_failed 0 0.00 Fetch failed n_srcaddr 0 .
