protocol failure in circuit setup

Receiving the above error from an application. I narrowed it down to a problem with rsh. If the rsh command is issued too rapidly it fails intermittently.

Try this script on your linux box...

#!/bin/sh -f
for i in 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20
do
echo $i
rsh `hostname` "echo $i" &
done

If you don't get the error right away, try running the script a few times in close succession.

I think the problem is with the /etc/xinetd.conf settings. Anyone know what flag or setting we have to tweek to avoid this problem?


Here's part of the output....

NAME
mailping-success - Munin plugin to graph time since last mail delivery SYNOPSIS
/usr/share/mailping/munin-plugins/mailping-success {[config] | ['']} DESCRIPTION
mailping-success is a Munin plugin that monitors time passed since last successful email probe. Configuration output When passed config, it outputs Munin configuration information. If there are no circuits defined (no subdirectories in /etc/mailping), it specifies that Munin should draw no graph either. If configuration files /etc/mailping/circuit/warntime and /etc/mailping/circuit/failtime exist, the values in them are passed on to Munin, for use in Nagios alert integration. Value output When passed an empty string '', mailping-success outputs the difference between current time and last successful probe, for each configured circuit. FILES
/etc/mailping/ List of circuits that exist; each subdirectory is a circuit. /etc/mailping/circuit/warntime If more than this many seconds have passed since last successful probe, a Nagios warning is triggered by Munin (assuming it has been configured to do that). Default: no warnings. /etc/mailping/circuit/failtime If more than this many seconds have passed since last successful probe, a Nagios alert is triggered by Munin (assuming it has been configured to do that). Default: no alerts. /var/lib/mailping/state/circuit/success Timestamp in seconds of the last successful probe for circuit. ENVIRONMENT
MAILPING_CONFIGDIR Override the location of the configuration directory. Default: /etc/mailping MAILPING_STATEDIR Override the location of the state directory. Circuit states are stored in the state subdirectory of this directory, in subdirectories named after the circuit name. Default: /var/lib/mailping SEE ALSO
