[SOLVED] Raspberry Pi 2 Randomly Crashes/Reboots

Well...certainly didn't expect this...the Pi is still running. And at a nice cool 42.8 C. It didn't look that way, but maybe the power supply was loose from the wall? Anyway, going to test this further. If it crashes again, you guys will be second to know.

We had crashing issues with a Pi and found that the particular distro that had been installed had created a swap volume on the SD card. Stopped the use of swap and we've been fine ever since.

May be unrelated, but might think about this for your next check.

Yeah, there is no swap on the card.

From what I can see, it's still running, so we'll see...

Power...

You can check the actual voltage available to the device by using a volt meter, connecting the positive lead to the solder points pp1, pp2, or f1 and the negative to the housing for the USB ports. You need at least 4.8 volts. According to the specifications the USB ports deliver 600mA/1.2A.

The power supply may be producing 5 volts, but the cable has to have current carrying wires of at least AWG 24.

Are you using the GPIO connection? Voltage here should measure 3.3 volts. However, there is only 50mA available in all.

As far as I know. But I haven't had the issue in about a week, which would suggest a loose cable/power block. Whatever I did to try to troubleshoot it inadvertently fixed it, if only temporarily. Like I said in #16, I'll post again if it reboots.
So far so good though.

Hi,

For my Pi setups, I use separate power sources for peripheral equipment. Easy to do with proper source and Pi supplies. I use a power strip to source all supplies and convenient to switch on/off the Pi & equipment or to be certain of power control to prevent inadvertent switching things off. I do use external drives and have not experienced any issues with this setup. I found some 4 port USB chargers that fit my needs for supplies for this setup.

One note is to be sure to have a good air flow around the equipment. Adafruit case is left open with the top case removed. The units are fixed to a board to insure positive positions on the bench using Velcro. I thought about putting a small fan close to the PI to insure air flow across. If you plan on overclocking then a small heat sink could be used but the Adafruit top case would have to be cut out to allow this. This would depend on the heat sink fins height and area. I have some GPU sinks that would fit the need but with the new Rpi 3 available then I should purchase and replace the RPi B+. Move B+ to other uses. I now have 3 RPi's doing various duties.

Hope this helps.
Have fun & enjoy!

Sorry, I have to admit I am amused by a post suggesting that the Pi may need the case top removed and more air-flow over it in order to keep it at a suitable temperature.
This is not because I think the advise is not good but, rather, because I live in a country where the ambient temperature of the device will hit 35C (95F) so the actual device would likely only hit a temperature to be concerned about if severely overclocked in a case with no ventilation at all.

Well, thought I'd post a little update on this. The Pi is still running and has been ever since I posted last. Dunno what it was, but I'm pretty sure it's not a problem anymore.
Marking this thread as solved, even though I really didn't solve anything.

Thanks for the update.

A good guess is enough here.

Anything changed since your last post? Power supply undated? Load changes?

Other than a layer of dust on top, no.

So far the only thing that had crashed mine have been power supplies. Some are marked as 2A but when the Pi is under a heavy load such as copying a large amount of data they still let the voltage sag.

I've found these to be the best

WRT laptop batteries being destroyed by heat, heat is a factor. A typical Lithium ion will loose ~10% of its capacity each year or as high as 20% if kept hot. However most decent laptops will keep the heat away from the battery where cheaper ones might not. So your battery is going to die soon anyway, how soon depends on how well the laptop was designed. You may as well just use it.
