3+ million items queued and changing extremely slowly

I am selectively syncing a small-ish part of an 6TB (and growing) account to my linux laptop (latest insync release). Items queued or remaining is at ~3 million and keeps growing more than it is shrinking. At the current rate I calculate that it would literally take the remainder of my life to complete. The database in ~/.config/Insync/dbs is 9.2GB and growing so it would be difficult to upload (which seems to be supports main response to all issues). On another laptop with a fresh install, I am not having these problems (and dbs is much smaller). This would seem to suggest I start over and wait forever for files to re-download. This is causing a huge decrease in my productivity so help would be welcome.

Please send us your logs.db and out.txt file to support@insynchq.com. Please also include the link of this post.

Thank you.
