Major Onedrive Business client continuous sync loop bug
Yes, I'm seeing the exact same thing over the past few weeks. It appears to be the most recent version of OneDrive that was installed (17.3.6943.0625), which also happened around the same time my laptop was forced to update to the Creator's Update. Randomly (it seems), when I login to my computer, OneDrive feels like it needs to resync some or all of the 12GB of sharepoint folders that I have synced. I have 3 sites synced, and it doesn't always resync all of them, but usually at least 7GB of something. It is driving me crazy, and several other people in our office are experiencing it as well.
How did you identify the files that were the culprit? Someone else recommended the I tried the Support and Recovery Assistant and thought it was related to OneNote, but that tool found no issues for me.
Is there any way to go back to an old version? Is there any hope on the horizon for a fix for this? As you have said, this is not good for my SSD drive, and it's also not good for my home/office bandwidth usage.
Couple of points (mostly in reply to OP):
First point - this has actually been a "problem" for a considerable amount of time, I recall certainly throughout 2016 as encountering this (personal OneDrive with iTunes library configuration stored there - iTunes causes a write lock throughout the time it's running). Any write lock will cause OneDrive to loop through looking for changed files, as it's reacting to writes. Consequently, I'm not convinced searching for an older client will help.
Most straight-forward way to find the files is looking at the explorer file badges; folders and files with locks will constantly have the blue sync badge over their icon.
Second point - the bit about destroying SSD through NAND writes is completely wrong. If you actually look at the procmon results you'll see the desired access for every file is Read/List + Read Attributes. Additionally, it's not hundreds of gigabytes worth of data since it's just scraping the properties for the file to work out what's changed. You can confirm this by loading up Resource Manager, hitting the Disk tab and (if it even appears) selecting OneDrive.exe.
CPU nor disk performance never spirals out of control, so don't see this as being much of an operational issue.
