Problem

--The following warning message repeatedly appears in SUP.out:

Warning - connections(R): supConn=AAA, supConnMax=BBB, ftConn=CCC, ftConnMax=DDD, rsConn=EEE, rsConnMax=FFF, rsId='GGG'

What is the cause of this message, and what can be done to prevent it?

Resolution

* This indicates that Gateway has reached its limit on one of the settings controlling how many responder connections (Gateway as server) are allowed. There are several such maximums: global settings defined for SUP, per-protocol settings, and per-site settings. If any of these are reached, Gateway will be unable to respond to new connections.

* The placeholders AAA through GGG above represent the following:

AAA - current number of responder connections

BBB - maximum global number of responder connections allowed (peluconf get -s monitor resp_conn_max)

CCC - current number of open connections via the given protocol

DDD - maximum number of connections allowed via the given protocol (peluconf get -s ft_PROTO resp_conn_max, where PROTO is ftp, http, phse, etc.)

EEE - current number of open connections using the given remote site

FFF - maximum number of connections allowed using the given remote site (peldsp display_site -a ALIAS|grep s_resp_conn_max)

GGG - the remote site's alias

Thus, if for example rsConn is equal to rsConnMax, then it means that the maximum number of simultaneous connections to this site has been reached, and it will be necessary to either raise the s_resp_conn_max setting for the site (via Navigator, it's the "Maximum number of simultaneous connections allowed to this Site" setting under the site's Options tab) or reduce the number of simultaneous incoming connections.
