Hi,
After upgrading to 18.04 on my workstations recently, sometimes when copying a file to a cifs mounted samba3 share, the copy/move never stops and massive files get created filling up the file server.
I've filed a bug report, but am not sure where to continue:

Currently it's corrupting our files, which is causing to lose is work and/or time having to restore from backup where available.
Thanks
