9 years ago I have had same issues on both Pi and beaglebone black platforms - but not on laptop - so I am going to try using Radxa Rock to see if the extra ram onboard makes a difference. There must be a memory leak somewhere.
I also tried running as a crontab every 6 hours: sync; echo 3 > /proc/sys/vm/drop_caches
but still get crashes after several hours - most ive managed is 14 hours with blutooth and wifi plugins.

Has anyone seen any memory errors? i see these sometimes when running snoopy either for a few minutes. if it doesn't populate it's usually after snoopy has been running for a longer duration.
