Libreelec/Kodi Keeps Crashing

I am running Kodi 16.1 on Librelec 7.0.3 on a Raspberry Pi 2. I am experiencing a lot of crashes. Some of them are reproducible (accessing or installing an add-on). However it also occurred today while accessing media on a USB stick. I have reinstalled Libreelec/Kodi and have also swapped out the SD card for a different one, eliminating that as the issue. I know how to access the log files, but do not know how to read them to narrow down what the problem is. Any help would be appreciated.
