Just today, for the first time in a while, I have my Win machine
mounted on my linux machine.

But after a short while I'm seeing a large amount of read & write
network traffic between the two machines

Just today, for the first time in a while, I have my Win machine
mounted on my linux machine.

But after a short while I'm seeing a large amount of read & write
network traffic between the two machines.

If I unmount the share (essentially my entire
Win disk), it stops.  But otherwise, I see cifsd getting
100% of a cpu most of the time.

Is there a log like samba has to see what is being accessed?

I'm not sure at this point what is causing it...

(sorry for partial note before.  I swear I clicked on save, but 
must have hit send... (lame!)...

You can see some information (i/o in flight e.g.) in
/proc/fs/cifs/DebugData and /proc/fs/cifs/stats

You can enable logging (dmesg ie the kernel log) "echo 7 >
/proc/fs/cifs/cifsFYI")

See https://wiki.samba.org/index.php/LinuxCIFS_troubleshooting
