Subject: ip_conntrack & timing out of connections
Date: Tue, 6 Nov 2001 12:19:47 +0100 [thread overview]
Message-ID: <20011106121947.A678@schmorp.de> (raw)
linux-2.4.13-ac5 (other versions untested) has this peculiar behaviour: If I
"killall -STOP thttpd", I, of course, still get connection requests which
usually time out:
tcp 238 0 217.227.148.85:80 213.76.191.129:3120 CLOSE_WAIT
tcp 162 0 217.227.148.85:80 213.76.191.129:3128 CLOSE_WAIT
tcp 238 0 217.227.148.85:80 213.76.191.129:3136 CLOSE_WAIT
tcp 162 0 217.227.148.85:80 213.76.191.129:3152 CLOSE_WAIT
tcp 134 0 217.227.148.85:80 66.42.121.15:3305 CLOSE_WAIT
tcp 162 0 217.227.148.85:80 213.76.191.129:3160 CLOSE_WAIT
tcp 279 0 217.227.148.85:80 62.83.11.19:2742 CLOSE_WAIT
however, after some time, I get many of these messages:
Nov 6 02:39:55 doom kernel: ip_conntrack: table full, dropping packet.
/proc/net/ip_conntrack has lots of connections like these:
tcp 6 430665 ESTABLISHED src=213.76.191.129 dst=217.227.148.85 sport=3881 dport=80 src=217.227.148.85 dst=213.76.191.129 sport=80 dport=388 1 [ASSURED] use=1
that is, connections to port 80. a grep dport=80 in ip_conntrack gives me
3768 lines, where netstat -t only shows 159 connections, so it seems that
conntrack has a problems with time-outs (or something similar).
