Constant Kernel Panic

[markophoto2013]

I'm running Lightroom CC and Photoshop CC and it's become a constant problem where when I am saving a photo in Photoshop with Lightroom open as well, the computer will experience a kernel panic and shut down.  The report seems to indicate that it is Lightroom that is causing the problem.  I'm running 10.12.5 on a 2017 iMac. Here is a look at the report.  Thanks in advance for any help.

Hi markophoto2013,

Sorry about the system shutdown and kernel based error you're getting while exporting/saving images from Lightroom and Photoshop.

Could you please check if the issue persists if you uncheck "use graphics processor" under Preferences> Performance menu in Lightroom?

Also, which exact version of Photoshop and Lightroom are you using?

Regards,

Akash

I've unchecked the graphics processor box and will see how it does.  Also I'm using PS CC 2017.1.1 and LR CC 2015.12.  I recently updated LR when this problem occurred but it didn't help.

[markophoto2013]

I just realized that when I thought I had updated LR I was actually installing the LR Classic app.  I'm having the problem with the LR 2015.12 app.

Indeed, the latest version of Lightroom and Photoshop are 7.3.1(Classic CC) and 19.1.4 respectively. I wonder if you're using the older versions for any specific reason? Try updating to the latest versions of both the apps and let us know if that helps.

Akash,

I've switched to Lightroom Classic and have the graphics processor turned off but I am still experiencing crashes.  Any ideas?

Thanks,
mark

Turning off the GPU will have no influence on this. On Macs that just isn't an issue and it definitely won't cause kernel panics. Kernel panics like you are seeing here are due to hardware issues or to some really deep lying software problems. From the kernel trace above iI would HIGHLY suspect the Symantec antivirus software you have loaded that is causing your crashes. You might want to get rid of that or make sure it is at the most recent version. Antivirus software in many cases is worse than what it attempts to cure.

Thanks for your input.  I'll try uninstalling Symantec.  I don't know how to read these panic reports but did you also see the line towards the top mentioning Lighroom?

Yes, that just means the main process running was Lightroom. Doesn't necessarily mean that that is what crashed the computer but could be a routine that it called. The possible cause indicated is rather unhelpful. Mutexes and spins are all over multithreaded programming. A mutex is an access "semaphore" that makes sure that regions of memory or files do not get written to by two threads at once. As you might imagine that is rather a generic thing so the trace doesn't tell us much. It dis show me you were using symantec AV software which is well known to cause kernel panics as it embeds itself in the kernel as a gatekeeper to all file access. Applications like Lightroom very strongly stresses such AV software because they do a lot of file access (to the catalog file, preview databases, etc.) and can expose bugs in the AV code easily that other software doesn't often show. Don't know if this is the issue but something worthwhile to try.

Jao, I uninstalled the Norton anti virus and have not had another kernel panic since then.  Thanks so much for your help and time.  I just marked your response as "correct" above.  No more lost work!

Glad to hear it!

My recommendation about what to do is start a brand new thread, describe the problem in detail, and provide all basic information, including:

Thank you 🙂 I have and I received no responses. I'll try again

And did you try the suggestions made already in this thread?
