HAProxy - dropping connections
frozenmsp last edited by
My first foray into HAProxy, and I've been bashing my head against a wall trying to sort this one out.
I've got a pfSense 2.4.2-p1 install w/ HAProxy going to 2 different internal servers. Both servers load just fine, and you can navigate and browse.
However, if you do anything that takes time on either one, the connections are interrupted and dropped. One is an internal project management app on an IIS server, the other is a file hosting server running Rumpus. Timeout shouldn't be an issue as I've set both to 20 minutes. Doesn't appear to be load related as CPU load is minimal (80% free).
Downloading a file through the file manager, it starts at full speed then after a few MB it drops steadily in speed until the browser eventually reports a connection error.
Any help would be appreciated.

Your server timeout is 2 minutes for the webapp, and a connect timeout shouldn't really be above 10 seconds, if it takes 10 seconds to get a working tcp connection there is some serious network issues even when accessing a server over the internet..
As for dropping established connections there could be different factors causing that.. Configuring the syslog on the haproxy settings tab(perhaps to the local syslog unixsocket) and enabling 'detailed logs' on the frontend should help tell if the client or server breaks the connection or a timeout is hit perhaps..
In case of doubt also run also capture the packets on both wan and lan side of haproxy to check with wireshark which side traffic gets interrupted.
