direct links of old sources may well be a few messages off.

Maybe network hiccups. I had some unexplainable problems during migrating drbd-devices to other clusters using the service IPs. Sometimes it worked, sometimes not.

After using

  net {
    data-integrity-alg crc32c; # crc32c, sha1, md5
  syncer {
    csums-alg crc32c; # crc32c, sha1, md5

in the configuration this sort of problems was away.
