90% CPU usage by readynasd
Good morning,
since an automatic and unplaned system shutdown the ReadyNas is very slow. Web access is also not possible.
Via SSH access I saw that the readynasd process needs full CPU power.
Process status shows, that the status is since days "importing DB". => No ActiveDirectory integration => at the moment no additional Apps are running (only btsync is installed but disabled at the moment).
systemctl status readynasd.service
● readynasd.service - ReadyNAS System Daemon
Loaded: loaded (/lib/systemd/system/readynasd.service; enabled; vendor preset: enabled)

I tried to fix it with apt-get update/upgrade => still hanging
I googled a long time and found many people with such problems, but no sloution fixed my problem.
Any ideas?
Mybe a firmware update via ssh?
I don't prefer to make a factory reset.
Thanks in advanced

Somehow (I have no idea how) your rsync config file had nul bytes in the middle of it. This cause our config parser to go into an infinite loop. I fixed the config file locally on your box, so you should be up and running normally. We will also have a firmware fix for handling this strange situation gracefully in 6.7.0.

Which firmware are you running?
Have you checked how full the root volume is?
# df -h # df -i
Good question regarding the firmware version. Is there a chance to find it out via SSH? I have no Web access.
Disk space I chacked already:

Nobody an idea?
From my point of view the disks are not to full.
