Default SRMA Problem SAMRecord contig does not match the current reference sequence contig


I am receiving the error "SAMRecord contig does not match the current reference sequence contig" and a subsequent program exit when trying to perform realignment on a sorted bam file. The error occurs somewhere near the completion of processing the first chromosome (chr10). I have seen a previous post where the problem was caused by the SAM header order differing from the order of the headers in the reference fasta file but this doesn't seem to explain my problem.

The headers from the sam file used to generate the bam look like this:

ANd the reference file headers look like this:


Any ideas what could be causing the problem?
