Why is cnid_metad loading the cpu?

Question

linux

Hello!
OS: Ubuntu 14.04.3 x64
Recently, the laptop has become super-strong (up to 60 degrees) and the fan is noisy.
top shows the cnid_metad process eating ~96% of resources.
I thought it was a demon

cnid_metad waits for requests from afpd to start up instances of the cnid_dbd daemon. It keeps track of the status of a cnid_dbd instance once started and will restart it if necessary. cnid_metad is normally started at boot time from /etc/rc or equivalent and runs until shutdown. afpd needs to be configured with the -cnidserver option in afpd.conf in order to access cnid_metad. It is possible to run more than one instance of cnid_metad on the same machine if different values ​​for the interface and/or port are specified with the -h and -p options.

I did sudo kill -9 cnid_metad, nothing seems to have broken, the load has decreased, the cooler is not noisy.
As far as I know, the process existed before, but there were no such loads. Advise whether it is possible to cut out a demon and how do you control processes?
