NAS326 won't respond

I own a NAS326 since December 2016. There are a few days now that my unit does not respond. When I try to login through my browser I get a "Site unreachable" error. The owncloud server that I use is not responsive either, and I cannot mount any of my shared to my linux machine.

The only way to login is by forcing a restart on NAS (unplug the power and plug it back in). For a few seconds after the restart I'm able to log-in and after a while everything freezes again. The CPU load is reported by the UI to be at 100% but the top command (via SSH) reports the CPU usage at around 5% to 15%. "Heaviest" processes are:  loop0, kworker, Python (not always in that order)

Also, the hard drive I've installed seems to be constantly working.

I have disabled the twonky media server and have only the owncloud and mysqlphpadmin packages installed.

Any ideas as to what the problem is? Any help would be much appreciated.

Regards,
A.

    The NAS runs 3 webservers, httpd, pkg_httpd and DAV_httpd, using ports 80 and 443, 5000 and 5001, and 5002 and 5003. Httpd (Apache) runs the main webinterface. pkg_httpd runs the webinterface of the packages, and looking at the name I think DAV_httpd runs webdav.

    So when pkg_httpd is consuming CPU, I think OwnCloud is being accessed. Is it accessible from outside?
    Using 'netstat -tpn' you can see all current connections.

    Top also shows you which python script is using most cycles. Which is that?

    Python was reported as "heavy" by the UI not top (sorry for the misunderstanding). I read somewhere that in that case "python is the UI"...
    However, I noticed the following behavior: Yesterday I unplugged the ethernet cable from the router and the HDD stopped working. Now I just plugged it back in and it started again... top reports that the "/i-data/.system/zy-pkgs/pkg_httpd -f /etc/pkg_service_conf/httpd2.conf" (several instances of it) is also consuming resources...

    You are right. OwnCloud was the culprit. Once I disabled it, the nas came back to normal. I'll try to debug it when I'll have a bit more time but for now I'l have to live without it :(

    Thanks for your help!
