Hi all,
as I can see in the logfile the patches are included in version 3.2.1:
Speedup to CGIs when lots of comments or downtimes in status.dat file (Jonathan
Kamens)
I attach the results of "nagios -s nagios.cfg" from unpatched 3.2.0
and 3.2.1 version. I think my monitored hosts and services are few to
see any difference!
