| |
I have several fairly busy servers reporting a negative value for tcp_tw_count. For example:
bash-2.05a# cat /proc/net/sockstat sockets: used 121 TCP: inuse 50 orphan 0 tw -65048 alloc 81 mem 26 UDP: inuse 15 RAW: inuse 1 FRAG: inuse 0 memory 0 bash-2.05a#
When I look at netstat -n, I see many (hundreds) connections stuck in TIME_WAIT. They've been there for at least a few hours, and probably much longer (days).
Is this expected behavior? A known bug?
FWIW, I'm using a RedHat kernel, 2.4.18-24.7.xsmp on a 2-processor Athlon system. If this looks like a bug I'll try to reproduce it with an unmodified kernel.
Thanks, John Salmon
