Re: [Nagios-devel] Re: FreeBSD thread issues

Please excuse the top-post...

I will make an offer again, anyone that needs access to a FreeBSD box for
development, please contact me. I have a 5.4 box that I can create a jail
on (ie: you can have a sandboxed root) and a 4.11 box as well.

Thanks,

Charles
