[smokeping-users] Holes in graphs

[Peter Kristolaitis]

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.

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.
