Bookmarks sync fails with "Error: Single record too large to submit to server"
Since some days I had the problem that my entire Firefox browser (not only an individual tab) was freezing for some seconds every few minutes. I now figured out that this was related to Firefox sync, which started to fail a few days ago and was triggered every few minutes.
The sync logs show errors similar to these:
1526892770098 Sync.Engine.Bookmarks DEBUG First sync, uploading all items

I then tried to create a new Firefox profile and to start sync all over again, which was also not working. I am operating a Mozilla Sync Server on one of my own private servers and in the server logs, I noticed that sync tried to fetch one million new bookmarks from the server until I cancelled the process after some hours.
After noticing that I had a look into my bookmarks. There I figured out that my bookmarks were completely screwed up. They were doubled and tripled in the "Other Bookmarks" folder and --- strangely --- they were somehow linked. So deleting a particular bookmark in the "Other Bookmarks" folder deleted it also in the "Bookmarks Toolbar" folder, for example. I decided to completely delete all bookmarks and restore them from a backup. Now, at least in the bookmark manager, everything seems fine.
I also deleted my Firefox sync account and registered again to delete all data on the server side and to start with a fresh sync. However, the sync is now still failing with errors similar to the one above.
Any help is appreciated.

Hi, I notice you do not mention another device at all. Sync is for Syncing 2 or more devices and is not designed as a backup service. Failure will happen sooner or later no matter what you do when using this service as a backup.

Hi, I am using more than 10 devices synced with this profile. However, I cannot see why this information should matter for solving this particular issue.
