Beats me? I?m really hitting in the dark here but: 1) Is there any possibility that you have circular symlinks, or symlink chains? I?m not sure how gracefully R would do with symlink chains. 2) Are there no permission issues on the bam/bai files or a subset of them? 3) Could it be that the symlink names are too long? That used to create problem in the distant past on some linux distro, but I have not seen it occurring in years.

Martin Also, I'm not sure how easyRNASeq does things, but it might be more natural to operate on a character() or BamFileList() created with the original file names spanning multiple directories.
