We recently installed Observium in an effort to replace our aging Cacti and Nagios systems.

We are running the latest code checked out of SVN (We paid the money to Adam for the Professional Version)

Today we added 180+ Adtran based devices to the system.  All 180+ devices began rebooting.  

They would become stable for a few hours and then start rebooting again.

Important to note that most of these items have been in our network for 3+ years, are running recent code, and have been rock solid stable for their entire service life.   Cacti and Nagios poll them every minute and have been doing so for the past 3 years.

Insert Observium and the devices start failing.

My initial feeling is that there is something in the way Observium does its SNMP.

Curious if anyone else has experienced this or something like this.  Its caused us to halt putting more devices on Observium.

Devices are TA 5000 / TA 352 GPON ONT's, TA 9xx iad's

When I add a single device via 

add_device <name>

and then do a

discover.php -h new

as soon as the code hits ENTITY-SENSOR-MIB  the adtran device reboots
