system rebooting several times while recording

Added by Neil Carter over 8 years ago

Greetings:

I'm running 4.0.8-3~gc870eb9~wheezy on a RaspBerry Pi model 2B. This records OTA in the US from a Hauppage WinTV 950Q USB tuner. The system has been stable for several months, until about a week ago, when it started rebooting several times during the recording of programs. This results in anywhere from two to six file segments being created with subsequent segment names being appended -1, -2, etc. Of course, there are gaps in the program due to the reboot time.

I've reviewed the /var/log/syslog files as well as the /var/log/messages files for the times involved, both attached, but find no real smoking guns. I do find log entries that make it sound like there's a possibility the tuner is to blame, so I've swapped out a spare identical tuner. We'll see what happens with that.

The root file system has about 1GB of storage free (on an 8GB SD card), which would seem to be fine. Recordings are stored on a 64GB USB thumb drive temporarily, which means the USB storage is kept empty normally. This means that the USB tuner has data incoming, being processed, and then written to USB storage. Can this be overloading the USB system? If so, odd that it should start doing this now. Is there any 'tuning' of the USB system? The Pi does pass the ethernet traffic through the USB system as well, so...

Note that sometimes the system still records an entire program with no issues (sometimes in the middle of a string of rebooting program recordings).

Any suggestions from anyone?

Thanks!

Neil

Check power source - I've had pi's work fine for hours then randomly reboot or die on me because the they kept drawing too much power.

Excellent tip!!

Thanks, Mark!

After reading your response, I remembered that I had added a new surge supressor/power strip to the entertainment center about the time this all started. Since I did not have a spare USB power brick with enough power to run the pi, I decided to move the brick out of the new strip, back into one of the older ones. As of this morning, all now seems fine. Recordings from last night are fully back to normal! Interesting scenario.

Again, thanks a million!!
