Hello again, So after wasting my time here I finally realized that apparently boltdb is archived upstream. It will not receive any fixes.
Apparently golang-github-coreos-bbolt is a maintained feature-extended fork. We should likely encurage moving to that and get boltdb removed from debian. The timeout waiting for db.mmaplock that occurred in boltdb is apparently already fixed in bbolt, see: https://github.com/etcd-io/bbolt/commit/e06ec0a754bc30c2e17ad871962e71635bf94d45 The pagesize issue seems to plague them both still though. See https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=976926 for the bug report against bbolt. Regards, Andreas Henriksson
