Non obvious 127 plugin error

[Craig Stewart]

Giorgio,

Here's the final command:

[1306952706.565337] [2048.1] [pid=3753]   Done.  Final output:
'/usr/lib/nagios/plugins/check_dig -H 72.45.111.250 -l www.xplornet.com
-a 142.166.86.46 -w 0.5 -c 1 -t 5'

I assume that's what you meant?

I'm also seeing this in the debug log:

[1306952721.202757] [016.1] [pid=3753] HOST: TS-WIN-DNS-1, SERVICE:
DNS-Check, CHECK TYPE: Active, OPTIONS: 0, SCHEDULED: Yes, RESCHEDULE:
Yes, EXITED OK: Yes, RETURN CODE: 127, OUTPUT: (null)

Simplify data backup and recovery for your virtual environment with vRanger. 
Installation's a snap, and flexible recovery options mean your data is safe,
secure and there when you need it. Data protection magic?
