I've got the same problem from a number of Ubuntu 16.04 machines. They're running on Hyper-V and so they've got the following installed as per Microsoft recommendations:
linux-virtual-lts-xenial linux-tools-virtual-lts-xenial linux-cloud- tools-virtual-lts-xenial It happens a few minutes after mounting an SMB share. The share eventually disconnects. I get the errors below on the console and it starts flooding our SMB share servers. In one instance, we connect to DFS shares so it is flooding the domain controllers. Errors seen on console: CIFS VFS: Autodisabling the use of server inode numbers on \\server\share. This server doesn't seem to support them properly. Hard dlinks will not be recognized on this mount. CIFS VFS: Error -104 sending data on the socket to server. Since I have the linux-virtual-lts-xenial kernel installed is there a virtual kernel I can upgrade to or just mainline? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1686099 Title: connection flood to port 445 on mounting cifs volume under kernel To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1686099/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
