First, the syntax of the check_command should be: check_smtp!25!60
And for that to work, the entry in your checkcommands.cfg would look like: # 'check_smtp' command definition define command{ command_name check_smtp command_line $USER1$/check_smtp -H $HOSTADDRESS$ -p $ARG1$ -t $ARG2$ } James Moseley Duane Hill <d.h...@yournetpl us.com> To Nagios-users@lists.sourceforge.net 01/05/2009 10:31 cc PM Subject [Nagios-users] Return code of 141 Please respond to is out of bounds - SMTP Monitor d.h...@yournetplu s.com Every once in a while I will get a critical alert stating: Notification Type: PROBLEM Service: SMTP Host: Secondary Spam Filter Address: 192.168.1.50 State: CRITICAL Date/Time: Tue Jan 6 00:43:01 UTC 2009 Additional Info: (Return code of 141 is out of bounds) I have the SMTP service defined as such: define service { ; smtp port 25 use ynp-services-duane host_name sec_spam_filt service_description SMTP check_command check_smtp!-p 25 -t 60 } I've checked list archives and have not found anything that closely resembles the issue at hand. What should I be looking for to correct this? Perhaps this is a FreeBSD port issue that needs to be reported to the port maintainer.
