When running bam-readcount I get (minus the 8M previous warnings of the same type):

So, I've read on line that such warnings can be ignored, however, only results on one position are produced

This error indicates that bam-readcount's internal mechanisms for caching per-read statistics are failing and that is likely the reason your results are incorrect. This is due to a bug in calling bam-readcount without requesting a region. For your case, a decent workaround may be to just request the entire "chromosome" like so: bam-readcount -f ref.fa your.bam GA21-EcoRV
