We usually do not recommend more than two USB FOB's per Pi but that was
not because of Pi crashes like you are seeing but rather because of the
potential of causing audio glitches when all were active.
You did not mention what version of software you were running at these
sites? Are you doing updates? The latest is V1.5.3-42. Also what FOB's and
what Pi's? 2B, 3B, 3B+? What power supply and are you using UPS's? Is the
power quality at the sites good?
Since as you say this seems to happen as a slowing of SSH can you run some
tests at that time like cpu_stats.sh, free, or top to see CPU and memory
usage. Also do you have any other programs or scripts running you installed
running on these servers?
