--- Comment #7 from Jason W. Bacon <jwb@freebsd.org> ---

Doesn't appear to be an mbuf issue.  Running the two scripts below
simultaneously:

#!/bin/sh -e

cd AD-VCFs-whi/MAF-0.01-1000nt
while true; do
    ls | grep 'combined.*\.vcf\.xz' | wc -l
    sleep 2
done

   11033
   11031
   11031
   11027
   11030
   11031
   11031
   11038
   11031
   11032

#!/bin/sh -e

while true; do
    vmstat -z | egrep 'ITEM|mbuf_cluster'
    sleep 1
done
