Client session file is full of “Can’t read netlink result from kernel.” lines

I am running:

 

Server: 64bit Ubuntu 20, NoMachine 7.6.2

Client: 64bit Ubuntu 18, NoMachine 7.6.2

After setting up and using NoMachine for a few days the hard drive of the client machine was at 100%.  The culprit was a 75GB session file under the .nx directory full of lines:

6272 6277 14:16:54 165.060 Socket: ERROR! Error is 42 ‘No message of desired type’.

Any ideas what is going on here?

On the connecting device try disabling MDNS. You can do this by going to Settings / Player / Security and unchecking the box “Don’t show other computers on the local network”.

Hello thank you for the response.  That box, and all other, was already unchecked.

Hi. Apologies, the box should be CHECKED in order to disable mDNS. 😛 If you’ll no longer see that log when the box is checked then we’ll know who is printing it, but not why it is happening. Are you using a custom kernel or a particular configuration or system security enforcing software?

[lhorner]

OK I think that has fixed things.  I do not see a growing file any more.  I do not run a custom kernel.  I am not knowingly running any security software but this company owned hardware and IT have root access.
