Hi:
Very sorry for the last email, it was an accident. Recently, I
trid to configure radosgw (0.94.7) with nginx as frontend, benchmark
it with cosbench. And I found a strange thing. My os-related
configuration are,
net.core.netdev_max_backlog = 1000
net.core.somaxconn = 1024
In rgw_main.cc, I see #define SOCKET_BACKLOG 1024. so here is the problem.
1、When I configure cosbench with 1000 workers , everything is OK. But
when it was 2000workers,there will be a lot of CLOSE_WAIT state
connections on rgw side, and rgw will no longer response to any
request.Use netstat command , I can see there are 1024 CLOSE_WAIT
connections.
2、I change net.core.somaxconn to 128, and run cosbench with 2000
workers again, very soon, there will be no response from radosgw, and
use netstat command , I can see there are 128 CLOSE_WAIT connections.
I tried a lot things, googled it , but the problem still exist. I
thought if there is some bug on fastcgi lib. Have anyone met this
problem?
