Dropbox is using an insane number of handles on my Windows 8.1 system. As of five minutes ago, it was using more than 175,000 handles. Most of them are 'Semaphore' handles. I've confirmed the number of handles with a few different tools.
If I close the Dropbox client and start it again, the number of handles starts off at about 4000 and ramps up quickly to 8000. Over the next few days it gradually climbs to 175,000+.
This excessive handle use by Dropbox doesn't seem to cause any problems, and the system continues to run just fine otherwise. But 175,000+ handles? That can't be good, and it's definitely not right.
I've found very little about this problem searching online. The consensus seems to be that I should do a complete Dropbox uninstall and reinstall.
