Hi, I have the same problem,
I'm using Solaris 10, Nagios 3.0.2 and the last version of NDOUtils. The data is stored in a Mysql.
Suddenly, the <defunct> processess start to appear. The load is:

Total: 65 processes, 154 lwps, load averages: 1.41, 1.50, 1.52

The Nagios service is degradating :


Services Actively Checked:
Time Frame Services Checked
<= 1 minute: 0 (0.0%)
<= 5 minutes: 495 (69.7%)
<= 15 minutes: 710 (100.0%)
<= 1 hour: 710 (100.0%)
Since program start:   710 (100.0%)

The nagios binary is linked to pthread...
No error messages are shown on /var/log/messages...
Any idea/suggestion?
Thanks in advance.

Does 'ldd /usr/local/bin/nagios' show it linked against libpthread or libthr?
