Hi Everyone. Problem: I got a trial emby on an OpenSUSE server. All looks good except the thumbnails usage. Every time I enter some folder thumbnail images are downloading again and it causes a 100% or high CPU usage. Already looked for a solution on the forum but can't find it. VM Hardware: 4 CPU Cores. 2 GB RAM. External mounted NAS with photos and videos of high resolution (~1TB). Also I use Nginx. Config: server { listen 80; server_name media.domain.com; root /var/www/html; return 301 https://$server_name$request_uri; } server { listen 443 ssl http2; server_name media.domain.com; root /var/www/html/emby; ssl_certificate /etc/nginx/ssl.crt/some.crt; ssl_certificate_key /etc/nginx/ssl.crt/some.key; location / { try_files $uri $uri/ @backend; } location @backend { proxy_pass http://127.0.0.1:8096; # Allow WebSocket connections via HTTP 201 proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; proxy_set_header X-Forwarded-Host $host; proxy_set_header X-Forwarded-Server $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Real-IP $remote_addr; proxy_redirect off; } } No errors in nginx log. /var/lib/emby/logs/embyserver.txt: 2020-09-08 02:00:03.484 Error ChapterImagesTask: Error during chapter image extraction for 2013-12-20 17.00 Annual Company Meeting, December 20, 2013, at 8000ms. 2020-09-08 02:00:03.484 Error ChapterImagesTask: Error during chapter image extraction for 2013-12-20 17.00 Annual Company Meeting, December 20, 2013, at 300000ms. 2020-09-08 02:00:03.484 Error ChapterImagesTask: Error during chapter image extraction for 2013-12-20 17.00 Annual Company Meeting, December 20, 2013, at 600000ms. 2020-09-08 02:00:03.484 Error ChapterImagesTask: Error during chapter image extraction for 2013-12-20 17.00 Annual Company Meeting, December 20, 2013, at 900000ms. 2020-09-08 02:00:03.484 Error ChapterImagesTask: Error during chapter image extraction for 2013-12-20 17.00 Annual Company Meeting, December 20, 2013, at 1200000ms. 2020-09-08 02:00:03.484 Error ChapterImagesTask: Error during chapter image extraction for 2013-12-20 17.00 Annual Company Meeting, December 20, 2013, at 1500000ms. 2020-09-08 02:00:03.484 Error ChapterImagesTask: Error during chapter image extraction for 2013-12-20 17.00 Annual Company Meeting, December 20, 2013, at 1800000ms. 2020-09-08 02:00:03.484 Error ChapterImagesTask: Error during chapter image extraction for 2013-12-20 17.00 Annual Company Meeting, December 20, 2013, at 2100000ms. 2020-09-08 02:00:03.484 Error ChapterImagesTask: Error during chapter image extraction for 2013-12-20 17.00 Annual Company Meeting, December 20, 2013, at 2400000ms. 2020-09-08 02:00:03.484 Error ChapterImagesTask: Error during chapter image extraction for 2013-12-20 17.00 Annual Company Meeting, December 20, 2013, at 2700000ms. 2020-09-08 02:00:03.484 Error ChapterImagesTask: Error during chapter image extraction for 2013-12-20 17.00 Annual Company Meeting, December 20, 2013, at 3000000ms. 2020-09-08 02:00:03.484 Error ChapterImagesTask: Error during chapter image extraction for 2013-12-20 17.00 Annual Company Meeting, December 20, 2013, at 3300000ms. 2020-09-08 02:00:03.484 Error ChapterImagesTask: Error during chapter image extraction for 2013-12-20 17.00 Annual Company Meeting, December 20, 2013, at 3600000ms. 2020-09-08 02:00:03.484 Error ChapterImagesTask: Error during chapter image extraction for 2013-12-20 17.00 Annual Company Meeting, December 20, 2013, at 3900000ms. 2020-09-08 02:00:03.484 Error ChapterImagesTask: Error during chapter image extraction for 2013-12-20 17.00 Annual Company Meeting, December 20, 2013, at 4200000ms. 2020-09-08 02:00:03.484 Error ChapterImagesTask: Error during chapter image extraction for 2013-12-20 17.00 Annual Company Meeting, December 20, 2013, at 4500000ms. 2020-09-08 02:00:03.484 Error ChapterImagesTask: Error during chapter image extraction for 2013-12-20 17.00 Annual Company Meeting, December 20, 2013, at 4800000ms. 2020-09-08 02:00:03.484 Error ChapterImagesTask: Error during chapter image extraction for 2013-12-20 17.00 Annual Company Meeting, December 20, 2013, at 5100000ms. 2020-09-08 02:00:03.484 Error ChapterImagesTask: Error during chapter image extraction for 2013-12-20 17.00 Annual Company Meeting, December 20, 2013, at 5400000ms. 2020-09-08 02:00:03.484 Error ChapterImagesTask: Error during chapter image extraction for 2013-12-20 17.00 Annual Company Meeting, December 20, 2013, at 5700000ms. 37M /media/cache/ 3.0G /media/metadata/ Please kindly help me.

I was just browsing the net and noticed that my PC's fan decided to speed up - this normally only happens when encoding video or playing games. I had a look at Task Manager to see what was using the most CPU and ntoskrnl.exe was using between 15 and 20%. I checked MediaBrowser's Scheduled Tasks and the Chapter Image Extraction had started running. I would have expected that to be using ffmpeg or something similar. Anyway, if I stop the extraction, then usage of ntoskrnl.exe goes down to 0%, restarting the extraction causes it to jump back up to around 20%. Is that expected behaviour?

For some reason since the last server update I have two FFProbe.exe tasks running on my server and they are both at about 50% cpu utilization. I've restarted the server and that doesn't seem to help. There is a Scan Media Library task running and it's running extremely slow. I'm wondering if something in the library is corrupt and it needs to be reset. Does anyone have any suggestions? I'm running Version 3.0.5115.35703 and up until very recently I haven't had any problems.
