samba causing disk activity every minute

I posted the following on July 2. No response. So I'm posting it here. This strace is from a fourth smbd process
This trace code runs for hours and hours. Though for some reason after a day or so it stopped. The network consists
of three my Clouds two windows 10 pro PC's and a Linux Debian 8 system usually turned off. Only the Public share on the
My Clouds is mapped to the windows PC's. Just as an aside do we issue the same system call in pairs or triplicate to compare the results?
I mean why do two or three gettimeofday one right after the other.
The latest version that Western Digital has shipped with the My cloud devices accesses the disk
about twice a minute. The access to /dev/sda2 is causing the system to keep the disk from going
into standby mode. I don't understand the call to quotactl every minute when no one is trying to access the share.
An strace of one of the processes shows the following:
