Lee,
A quick update on my RPi's.
The adsb unit is about to tick up 22 days and for the aprs gateway unit
with dixprs it's 18 days.
I'm finally starting to have confidence in the Pi for my 24/7 radio
applications.

Update - I didn't realize at the time I wrote the message below that the
AX25 interface had quit transmitting and receiving packets - it had quit
less than an hour before I sent the message. I had to kill the interface
on the Pi and restart it via kissattach, and then restart the AX25
interface in Xastir. At least this failure scenario didn't crash the
entire OS. There does seem to be an issue with AX25 networking in the
Raspbian distibution. For grins I have APRX running now as the IGate using
the same AX25 setup - we'll see how long it lasts.

Thanks Ray. My unstable setup was very similar to yours - Dixprs as the
IGate and AX25 networking on the Raspbian/Wheezy distro. It also included
a powered USB hub for the USB to serial adapter, USB enclosure with IDE
hard drive, and (sometimes) a keyboard & mouse. In theory I didn't need
the wired hub because the USB drive enclosure was powered, but I had
started with a laptop hard drive in a smaller HD enclosure that did need
the powered hub, so I just stuck with it, anyway. I was not using WiFi -
at least not directly. The wired Ethernet port was connected to a wireless
access point configured in client mode, so the AP handled the wireless
connection to the router. 10 days was very typical before a crash. In my
case it was not just networking - pretty much everything - had no access to
the Pi once it crashed.
My current setup, however has not changed from the above other than to run
Xastir as the IGate instead of Dixprs. It has now run for 20 days and
counting. I started out using a universal phone charger rated at
5.5v/800mA. Then I moved up to an "Amazon Basics" unit rated at
5.5v/2100mA, but nothing changed. Only changing the software has had an
impact.

I had terrible stability problems with a Pi in service as an aprs Igate.
Ten days was the best I could get out of it before a crash but the crash
could have been after a couple of hours or so. The installation was Wheezy
with kernel ax25 compiled on the machine and running dixprs as the gateway
software. The Pi drove an approved powered hub with 2A p/s and I used wi-fi
to access the LAN. It was the wi-fi that crashed every time. I moved away
from the Pi because I needed reliability. I had looked at power supply
issues, but obviously not in enough detail.
