Ligtroom Classic constantly crashing in ‘Finding People’ mode – problem resolved

[dicke64024227]

Lightroom classic started to crash constantly (within minutes) in ‘ Finding People’ mode.  Investigated problem in the usual way of adjusting/resetting preferences and catalogue settings, deleting and reinstalling Lightroom classic, creating a new small test catalogue of 700 images, but to no avail.  Ran Lightroom diagnostics, Event Viewer (/Windows logs/system), Task Manager for clues.  Noticed that ‘Finding People’ is a CPU-intensive activity (close to 100%).  Downloaded HWMonitor and discovered all CPU cores were running close to 100C.  Perused literature for solutions but thought it worthwhile to check grills on PC case.  Inlet grills were a series of small holes on both sides of the front panel and were partially/totally occluded.  A quick vacuum and re-ran ‘People Finder’ without problems on a catalogue of 25,000 files.  Noted CPU core temperatures were now running around 75C in a relatively warm room temperature of 30C.  I was surprised that so much dust had accumulated in the grills in a comparatively clean environment which was sufficient to affect the cooling of the CPU and the stability of the PC.  These observations may be a timely reminder for other users to check the grills of their PC cases for any obstructive dust accumulation.

What do you mean exactly with crash? Does it show you a message? If yes, what does it say?

Please also share the system information from the help menu.

The OP resolved the issue by cleaning the dust from inside the computer, thus allowing the fans to properly cool the CPU/GPU.

I know. IMHO, it would still be helpful for others to know more details.

And the system information could be helpful for a recommendation.

However, as it's solved for him ... all OK 😉
