Nagios 3.0rc3 can't execute plugins on NetBSD 4.0

[Magnus Bergroth]

Hi,

I have a new installation of Nagios 3.0rc3 on a NetBSD 4.0 Server. It has a
basic configuration just monitoring the local host. But it can't execute the
nagios plugins. I found that something goes wrong when 
run_async_service_check() in checks.c calls close_command_file(). If I
exclude close_command_file() it starts working. Going deeper, 
close_command_file() in utils.c calls shutdown_command_file_worker_thread()
that calls pthread_join(worker_threads[COMMAND_WORKER_THREAD],NULL).
Excluding pthread_join() and the plugins starts to work.

The call for close_command_file was added what I can see in rev 1.156 of 
checks.c. 

It looks like pthread on NetBSD dosen't work but as the close_command_file is
called from the child process should it call pthread_join?



The log nagios.log:
[1204817958] Warning: The check of service 'PING' on host 'localhost' looks
like it was orphaned (results never came back).  I'm scheduling an immediate
check of the service...
