Metashape Freezes - Kubuntu

[luisSeyfer]

Hello,
as titel describes Meteshape from time to time freezes my whole system.
It happens on heavy tasks, e.g. aligning 7 chunks with total 2500 images. (On the other hand what isn`t heavy in photogrammetry?)
After hard restart the system same task runs through without any trouble.

Are there any suggestions how to fix that?

Hello luisSeyfer,

Does it help to avoid such issues, if you save the project in PSX format before running any major processing stages?

Have you also checked the memory consumption graph during the processing and GPU load via resource monitor before the operation freezes?

[luisSeyfer]

Thanks so far. I did not have freezes since my posting. I will report if I encounter the problem again.

I had a freeze during Chunk Alignment. Unfortunately I didn't record memory.
I forced a reboot and restarted the process.
