+over 1229 and climbing as I type.
+
+It's git-annex version: 8.20210331-g1fb59a63a
+
+I've now stopped and restarted the 'git-annex get', but without `--jobs 4`, and this time it appears to have two zombie git processes, but it's not increasing as it gets more objects.
+
+I'm unsure how to debug what is wrong, so seeking guidance.
+
+Tomorrow I'll start to see if I can reproduce with older/newer versions of git-annex.
