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.
I'm using Dropbox v114.4.426.
I can no longer log in as the user I used to post this originally, and I have no idea why.
I have questions.
 What's a DropBox Basic plan, and how can I determine whether I'm 'on' a DropBox Basic plan?
 How do I know how many devices are connected?
I have multiple DropBox accounts, and I find managing them to be extraordinarily difficult. Is there a web page somewhere that explains how to handle multiple accounts?
I've reinstalled the Dropbox application as recommended. Handle use is at 7500 but remaining steady.
I'll add more information here as I continue to monitor things.
Handle use is now at 92,500 and rising. The clean reinstall did not help.
Is there anything else I can try?
Presumably, eventually Windows will run out of resources and crash. And there's no way to predict when that will happen. So, you know, it's working fine now, but it's going to start affecting everything at some point.
I'm working with the tier 2 support folks at Dropbox. If they can confirm that this is normal handle use by Dropbox, and that it's not a resource leak, that's good enough for me. Although it's using 20 times as many handles as the next closest application, and I'm running some heavy stuff, which like I said seems crazy.
