Very strange... my SmokePing machine at work is an old Pentium 4
2.66GHz with 1GB of RAM, and I run 7 pollers (1 default + 6 'real'
ones) over ~100 hosts with no problems. I have other stuff running on
the box as well (Cacti, mysqld, and some internally developed
tools). My machine is OpenBSD 4.4, though Linux shouldn't be much
different in terms of hardware requirements.<br>
<br>
I've rarely seen software cause hard lockups on a *NIX box; have you
checked for hardware problems? RAM, disk controllers, etc? Anything
showing up in dmesg? Maybe there's something that only starts to show
up when the machine is under load.<br>

noticed that when I try to daemonize Smokeping with the multi-poll set,
the system hangs up and locks out everyone. I had to hard reset the
server two times. I only have 3gb of memory installed on this server,
and the system has a 32bit proc. I had to revert back to my previous
setup. :(<o:p></o:p></span></p>
