Hey guys, We're running varnish 2.1 in two 64bit linux servers with 17Gb of ram. Here's the config we use:
varnishd -P /var/run/varnishd.pid -a 0.0.0.0:2000 -T 127.0.0.1:6082 -w 200,2000 -s malloc,12G -p lru_interval=20 -f /etc/varnish/varnish.vcl Suddenly the value of sms_nbytes in one of those went from 0 to 18446744073709550272. What does that mean? Other than that everything seems to be normal. Here's the output of varnishstat -1: client_conn 198874 7.77 Client connections accepted client_drop 0 0.00 Connection dropped, no sess/wrk client_req 1924202 75.17 Client requests received cache_hit 1292505 50.49 Cache hits cache_hitpass 0 0.00 Cache hits for pass cache_miss 607985 23.75 Cache misses backend_conn 605971 23.67 Backend conn. success backend_unhealthy 0 0.00 Backend conn. not attempted backend_busy 0 0.00 Backend conn. too many backend_fail 281 0.01 Backend conn. failures backend_reuse 1867 0.07 Backend conn. reuses backend_toolate 0 0.00 Backend conn. was closed backend_recycle 1867 0.07 Backend conn. recycles backend_unused 0 0.00 Backend conn. unused fetch_head 0 0.00 Fetch head fetch_length 579004 22.62 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 28803 1.13 Fetch wanted close fetch_oldhttp 0 0.00 Fetch pre HTTP/1.1 closed fetch_zero 0 0.00 Fetch zero len fetch_failed 3 0.00 Fetch failed n_sess_mem 148 .
