Nagios reporting no output when there is output

[Jean-Michel Philippon-Nadeau]

Hi,

	I have a strange problem with our Nagios installation. One machine in 
particular is always reporting a failure when everything should be OK. 
The machines pushes the service's status with NCSA. Here is what I see 
in my nagios.log file:

[...]
[1242408603] EXTERNAL COMMAND: 
PROCESS_SERVICE_CHECK_RESULT;<machine-name>;DISK;0;DISK OK [16025780 kB 
(85%) free on /dev/sda1]***DISK OK [37406088 kB (99%) free on 
/dev/sda2]***DISK OK [48949140 kB (99%) free on /dev/sda5]***
[1242408777] SERVICE ALERT: <machine-name>;DISK;WARNING;SOFT;1;(No output!)
[1242408837] SERVICE ALERT: <machine-name>;DISK;WARNING;SOFT;2;(No output!)
[1242408897] SERVICE ALERT: <machine-name>;DISK;WARNING;HARD;3;(No output!)
[1242408897] SERVICE NOTIFICATION: 
<contact-name>;<machine-name>;DISK;WARNING;notify-by-email;(No output!)
[...]

Additionnal information:

Both machines are running CentOS 5.3 (fully updated).
It is Nagios version 2.9

What could be the cause of such a problem?

Thanks,
