NAS constantly at 100% CPU, even if nothing happens

Whaytom · September 20, 2015, 2:18pm

Hey guys

I have recently installed Syncthing (current version: 0.11.25) on my Synology DS215j. It is fairly low powered (DualCore 800MHz, 512MB Ram) so i expected the inital sync to be slow. But I hoped it would speed up afterwards. My Plan is to use my NAS as a central point to sync my PC and my Laptop. That way these two sync even if I do not have both powered on at the same time. My Projects folder I want to Sync has ~100k Files which are 150GB total. The initial sync took ~30h. But even afterwards the cpu usage of my NAS stayed at 100%… My PC is turned on, but no file in the synched directory is changing.

Why is this happening? I already set the rescan Intervall to 6000s. I do not expect any files to change directly on the Nas, just via syncing.

I figured I might be able to use a Raspberry Pi 2 as my central Syncthing instance. Would this work better? It would still store the files on my nas via lan. I would have to buy one, so I can’t check yet.

Also I noticed the status indicator for my synced folder was broken during the initial sync. I had both webinterfaces closed (in hopes of speeding up the process). Whenever I opened the interface on my nas, it showed status “unknown” for my synced folder and listed 0 Files. It took a few minutes to show anything. This made tracking the process quite annoying.

Thanks for any help!

Change the ping-timeout to a higher value. In advanced settings (Action->Advanced or similar)

We should really open a troubleshooting guide I guess.

There were a few Ping Timeout before. I have now raised the Timeout limit to 600s and am not getting any timeouts. But the Problem remains.

I enabled debugging to see what syncthing is doing. For about an Hour it is like this:
