[smokeping-users] Sporadic crashes on reload in Smokeping.pm

[Vinny_Abello at Dell.com]

Hello,

I've been noticing on one of our smokeping installations running smokeping 2.6.8 on FreeBSD 8.3 (from ports), that occasionally after a reload of smokeping, it will crash in the following manner according to the log:

Tue Jun  4 11:55:34 2013 - Reloading configuration.
Tue Jun  4 11:56:00 2013 - Got HUP signal, exiting gracefully.

Tue Jun  4 11:56:00 2013 - Can't call method "step" on an undefined value at /usr/local/smokeping/lib/Smokeping.pm line 4284.

This definitely does not happen every time we reload it and we don't do anything to correct it other than start it back up again using the rc script and it runs fine. Any clues as to what might be causing this to happen on occasion and how to fix it? We currently have about 1067 targets defined and it normally finishes probing them all without issue every 300 seconds.

Thanks!
