If the problem still exists, change the tag 'verification-needed-yakkety' to 'verification-failed- yakkety'.

As a workaround, I've added a cron job that does a directory listing on the share every minute. It has not stopped the flood but it seems to be allowing the cifs client to stay connected for a longer period of time (a major annoyance when the application relies on that share being available.) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1686099 Title: connection flood to port 445 on mounting cifs volume under kernel Status in Linux: New Status in linux package in Ubuntu: Confirmed Bug description: This is identical to the bug reported on the Debian kernel list, only I'm running 4.4.0, not 4.[89].0 After about 15 mintues, the cifsd daemon starts flooding echo requests on port 445 to the windows server causing a constant 1MB/s load (around 10,000 packets per second) that eventually leads to system instability that forces a reboot to correct.

[Kernel-packages] [Bug 1686099] Re: connection flood to port 445 on mounting cifs volume under kernel
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 Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1686099 Title: connection flood to port 445 on mounting cifs volume under kernel Status in Linux: New Status in linux package in Ubuntu: Confirmed Bug description: This is identical to the bug reported on the Debian kernel list, only I'm running 4.4.0, not 4.[89].0 After about 15 mintues, the cifsd daemon starts flooding echo requests on port 445 to the windows server causing a constant 1MB/s load (around 10,000 packets per second) that eventually leads to system instability that forces a reboot to correct.

[Kernel-packages] [Bug 1686099] Re: connection flood to port 445 on mounting cifs volume under kernel
I've got the same flood here, on port 445, across my LAN. If I block that port, I get a flood instead via port 139. There was 1MB/s upload/download between my Windows 10 machine and a Raspberry Pi 3 (4.9.24-v7+). I blocked that and had the same flood between two Raspberry Pi 3s. The same thing happened if I fired up my Lubuntu boxes (I can't remember if it was the 4.4.0-75-generic or the 4.8.0-29-generic, and I can't re- enable Samba right now on the network, as it's "live" and I don't want to disrupt the web service). Have had to temporarily block all 139/445 Samba traffic on all networked machines, just allowing 139 and 445 from my Windows 10 machine, which is tolerable, as I need to be able to access network shared folders.
