Hidden Dropbox logs folder is stuck, continually growing bigger, now beyond 300GB

razzamatazz​ thanks for flagging

We're aware of this issue and its actively being worked on, although I can't provide a timeline for updates I'll circle back in this thread when we know more. 

Same issue here on macOS Sequoia 15.7.2, Dropbox version 239.4.8301

I discovered today that my .dropbox/logs/1 folder had grown to 123 GB (65,535 files at ~1 MB each), completely filling my 500 GB drive.

After clearing the logs, they started growing again immediately — 1.6 GB within 15 minutes, even with Dropbox just doing a normal sync of ~70 files in the background.

Key observations:

• Dropbox process shows 100% CPU usage and ~8 GB RAM while this happens
• Logs continue to grow even after "quitting" Dropbox (helper processes stay alive)
• Had to use `pkill -9 -f Dropbox`  to fully stop it
• This is a recent issue — never seen this in years of using Dropbox

This appears to be a regression in a recent Dropbox update. The logging is completely out of control and there's no log rotation happening.

For now I'm forced to keep Dropbox closed and periodically run cleanup scripts to delete the logs folder. This is not a sustainable workaround.

Please escalate this to engineering — multiple users are being affected and it's filling up drives overnight.

Dropbox filled up my hard drive with logs last night. It keeps continually creating new log files. I'm on Linux Mint:

$ ls .dropbox/logs/1/ | wc -l
20986
~ $ ls .dropbox/logs/1/ | wc -l
21210

I have solved the problem. I just deleted all the log files in Dropbox, and then logged out of my account from within Dropbox. Then I logged into my account again, and Dropbox re-indexed the files by itself. Now the space size is back to normal.

For anyone still dealing with this issue, I finally found a workaround that works.

1. Install this old build from Dropbox: https://www.dropboxforum.com/discussions/101003016/stable-build-233-4-4938/846954
2. Prevent Dropbox auto update from replacing this build. On macOS, you can use: sudo chflags -R uchg /path/to/Dropbox.app (to later undo this once Dropbox releases a fix, you can use sudo chflags -R nouchg /path/to/Dropbox.app)

The logs folder will initially grow a bit (but not nearly the amount and at the same rate it currently does), and will reduce in size once all is in sync again.

Adding in here that I've been experiencing this issue for over 6 weeks now too. Same exact problem. I've been using Dropbox for at least 10 years. Support has indicated this is a bug without a timeline for a fix.

Extremely frustrating and reckless to have a bug like this without a workaround or a fix for paying customers who heavily rely on Dropbox.

After this started happening again yesterday I'd forgotten to disable 'run Dropbox at startup' and today once again the log files completely filled my C: drive causing Ableton Live to crash and corrupt the configuration file due to not being able to save and yet again lost all my carefully setup plugin favourite folders etc, sample locations etc.

So incredibly frustrating and annoying. Please fix this.

I should add that not a single file has been synced while these 10's of GB's of files have been created. This is clearly a bug yet it's not being acknowledged while we all act as QA for you.

I'm still having this issue and a reinstall hasn't fixed it. At the point I'm no longer able to use dropbox effectively.
