Hi, everybody.
I can't understand the nature of the exact error on my samba-server. I'd
be very thanksfull for some help...

Here's situation:

One Linux-server (CentOS 7.2) with Samba and a network of 14 noteboks
(win 10). At some point, during working day, smb starts dumping core and
syslog giving us the following:

As well as I understand, the problem may be in ehternet-adapters of
notebooks... but how to understand the exact point of problem? Maybe
some samba network-related settings?

Thanks a Lot.
