Subject: EmbryonicRsts between two Linux boxes
Date: Fri, 21 Mar 2003 19:17:06 +0100 [thread overview]
Message-ID: <20030321181706.GD1103@udine> (raw)
Hi,
I have three Linux boxes on the same physical network. One runs a web
server (webfs) and the other two run an HTTP traffic generator. Under
high load, with many simultaneous open connections (~1000) one of the
clients gets a TCP RST ("read: Connection reset by peer").
netstat -s on the server box gives:
...
TcpExt:
3002 resets received for embryonic SYN_RECV sockets
...
Which, if I understand correctly, means that the server TCP stack
receives a SYN|ACK or a RST|ACK from one of the clients for a
SYN_RECV socket.
How can this happen?
Thx.
PS: there's 100ms network latency between the server and the clients
(emulated by NistNet). And I want to saturate the server. That's the
reason I need so many simultaneous connections.
