[389-users] Connections not closing
Hi,
I have an issue with our Fedora Consumers running 1.2.0 on Fedora 10 in
that they don't seem to be closing old connections and so the open
connections are building up until performance is impacted and eventually
we run out of file handles.
Looking at one consumer netstat is showing 711 Established connections
to port 389 from a Radius server, and the console is also reporting over
700 "Open Connections". Yet on the Radius server I see 3 Established
connections which is what I would expect. It seems each time the Radius
server restarts (which it does often to pickup config changes) then the
old connections timeout on the Radius server but remain Established on
the Fedora side. We do see the same behaviour from other services such
as mail and web servers but Radius is the worst due to it restarting
regularly.
On the console I have currently configured an Idle Timeout of 300
seconds and added timeout config to the Fedora OS:
tcp_keepalive_time = 600
tcp_keepalive_intvl = 75
tcp_keepalive_probes = 9
Why are these connections not timing out after the Idle time? At the
moment I am having to regularly restart the directory service in order
to clear the connections down.
Thanks.
Jim.
