I had the same problem and fixed it by going into System Preferences/Spotlight/Privacy. You can add an area that you do not want Spotlight to search. I added Dropbox and I have not had anymore mdworker system crashes and my system is much faster.
If you need to search in your Dropbox, there is third-party software for that.
Worked for me.
I'm having this issue with smartsync and High Sierra (10.13.6). I did what you said (unlink and link it back), but I also tried other solutions: rebuild spotlight; fixing system permissions; reinstalling MacOS. Nothing works: mdworker is constantly crashing, which makes "ReportCrash" process taking enormous CPU usage.
Maybe the problem got back woth your latest Dropbox release. Please find a sollution: I cannot work without spotlight making its job.
Sorry to hear you're still seeing this @afonsopatrao.
As you've already done some troubleshooting, could you perform a clean, advanced re-install and let me know if the issue persists?
If it does, could I reach out to your Dropbox email address to work on this together?
Yes, please. The problem keeps happening with smart sync. When I restart the computer, mdworker doesn't crash for some minutes. But as soon as I start to work on files, it crashes. And spotlight only works correctly with local downloaded files.
Thanks for letting me know and sorry to hear this persists even after an advanced re-install @afonsopatrao.
I have just sent you a brief message to your Dropbox associated email address so we can have a further look into this with all of my tools available.
Whenever you get the chance, take a look at your inbox and we'll take it from there.
Thanks so much!
Sorry to hear this @RafaelG. Have you tried any troubleshooting steps so far like re-installing the software on the affected device?
If the issue persists, could you post a screenshot of the exact error you see on your screen so we can investigate further?
Thanks so much and welcome to our Community too Rafael!
Hi I too am having this problem.
I have been communicating with Dropbox Tech support for some time and now my problem has been escalated. Since then I have had no updates or contact for six days.
I really need to get this fixed. "mdworker quit unexpectedly" and "quicklookd quit unexpectedly while using the DropBoxQL plug in"
It's driving me bonkers and stopping me from working effectively.
Can someone help?
I'm sorry to hear you're facing this issue and thanks for flagging this with us @ERC.
I understand that you're in direct line with our advanced team and haven't heard from them for days so I've passed your comments on to your ticket and gave it a nudge so as to be prioritized.
Thanks in advance for your patience and cooperation.
PS: In the meantime, you could try re-indexing Spotlight and/or force quitting and relaunching Finder.
After struggling with this for weeks and trying all kind of possible solutions, I finally got rid of the error message. The trick on my system was, to exclude the Dropbox cache folder from spotlight searches. Bingo. 🙂
