BeagleBone Black Industrial not always booting from microSD-card

Hello!
We have encountered some problems with our BeagleBone Black running on read-only SD-cards.
We have been running >10 Beaglebone:s with this setup for more then 6 months. After some time they have started to get some issues with booting from the external microSD-card.
Is there some known issues with the BeagleBone image we have used? Have I maybe chosen the wrong Image for BeagleBone Black?
