Thanks Chris
Yep I have plenty out there too with no issues. It also happened on a
Qotom box so not hardware related.

*Subject: *Re: [Astlinux-users] APU2 keeps locking up
for whatever its worth.. from a hardware standpoint I have probably 200
APU2s in the field and dont have then just freeze like that.. granted
they arent running astlinux, but just mentioning it from a power /
hardware point of view.
mine are all running Centos 6.X and asterisk 11 or 13
I have had a few chan_sip freezes.. (we wrote a watchdog to catch those
and restart asterisk).. we get maybe 1 every 3 or 4 months .. (not each
site but collectively)
I have kenrel panicked an APU before by upping and downing the ethernet
port too much (or so it seems).. it doesnt happen very often and is
hard to repeat in the lab. but have done it esp on an install.. where
one is prone to plug and unplug cables multiple times in succession for
dressing in..
I have had a few power bricks go bad.. in all cases there was just no
output.. no lights on the board at all. its not been that many 3 or
4.. considering we have sites in some pretty lightning-prone areas i
dont feel too bad about a few power bricks.
we run UPSs on all of our sites
we run the US power supply that is sold on the PC-Engines store.

Yep I would say environmental for 1, maybe 2 sites but for 3 sites and
all only recently I cant see how it could be.
No serial or long ethernet cables are connected.
Yes completely different power adaptors when I changed from APU2 -> Qotom.
Yes they are all DSL however ALL different modems and service types.
I'm thinking I will upgrade all Runnix versions at these sites and if
still happening upgrade to 1.3.10 and if still happening then I have no
idea what to do.

So a UPS may solve the issue as with Site 1 ?
Do you have any serial cables connected ?
Any long ethernet cables connected ?
Is this with a variety of power adapters ? ie. the APU2 -> Qotom
switch did the power adapter change as well ?
Sure sounds environmental to me.
I've seen DC-to-DC UPSs for about $40 USD, but never tried one.
