Hi,
I used varnish-cache-3.0.3-plus(get from
https://github.com/mbgrydeland/varnish-cache/tree/3.0.3-plus).
I use persistent storage and "set beresp.do_stream = true".
The %CPU is increased from 4% to 800% (8 cpu), and varnish crashed
sometimes by errno = 12 (Cannot allocate memory).
my startup command is:
/opt/ace/cache/varnish-cache-3.0.3-plus/sbin/varnishd -f
/opt/ace/cache/varnish-stream.vcl -s
persistent,/opt/ace/file/varnish_cache_persistent.data,12G -T 127.0.0.1:2000-a
0.0.0.0:8080 -p thread_pool_min 200 -p thread_pool_max 2000 -p
thread_pool_add_delay 2 -p session_linger 100 -p thread_pools 2 -p
http_req_hdr_len 32768 -p http_resp_hdr_len 32768 -p http_max_hdr 256
Then I change the command to:
/opt/ace/cache/varnish-cache-3.0.3-plus/sbin/varnishd -f
/opt/ace/cache/varnish-stream.vcl -s
persistent,/opt/ace/file/varnish_cache_persistent.data,12G -T 127.0.0.1:2000-a
0.0.0.0:8080 *-h classic,500009* -p thread_pool_min 200 -p thread_pool_max
2000 -p thread_pool_add_delay 2 -p session_linger 100 -p thread_pools 2 -p
http_req_hdr_len 32768 -p http_resp_hdr_len 32768 -p http_max_hdr 256 *-p
lru_interval 3600*
The %CPU is increasing too, but varnish hasn't crashed for 16 hours.
Is there somebody has experience about this problem?
Any advice will be greatly appreciated.
Here is the information about system and varnish.
