Samba's nmbd constantly performs disk io

Hello,

nmbd process (part of Samba package) constantly performs disk writes:

[root@kw al]# pidstat -dl 20

Is such behaviour (if it's occuring in 24/7 mode) causing additional significant disk weariness? (Usual rotational hard drive, not SSD.) If so, is there a way to tune it off?

Thanks.
