Oddly enough, the problem also seems to exist in 5.4, which features a
much improved thread library. There were also a few posts that basically
said that Nagios was not following spec. This one states it most simply:
http://marc.theaimsgroup.com/?l=freebsd ... 804481&w=2
"I don't know what Nagios does just after fork(2), it would be worth to
check. It appears that fork(2)ing without exec(2)ing or _exit(2)ing
in a pthreaded program is not a "valid" behaviour, regarding to
SUSv3 [1]. I don't want to avoid admitting there is a problem in
FreeBSD threading library, I don't know how other OSes handle this,
but Nagios folks should really avoid doing what is explicitely
dissuaded in SUSv3."

I did contact him directly, and then posted a summary of the responses
from the -hackers list here, but have not heard anything back. I do know
that there are some very friendly and helpful people on that list willing
to help, and probably a few Nagios users. The Nagios port maintainer for
FreeBSD ([email protected]) would also be a good contact.

That was just boastful baiting, it's safe to ignore and best left on
Slashdot with the "BSD is dying, Netcraft confirms" childishness, it's
best to ignore that sort of "advocacy".
