What are the FlexnetFS files created under /dev/shm?

[#1]

As part of normal operation, Flexnet Publisher may create and delete folders under /dev/shm with names beginning 'FlexNetFs.'.

These folders are associated with the implementation of the new secure file anchoring functionality on Linux.
They are not designed to be accessed other than by Flexnet Publisher, consequently, errors as below may be reported when trying to list such a folder are to be expected:

 ls /dev/shm/ -al
ls: cannot access /dev/shm/FlexNetFs.43054: Transport endpoint is not connected
total 99
drwxrwxrwt 3 root root 120 Mar 14 12:10 .
drwxr-xr-x 18 root root 3760 Mar 14 11:10 ..
d????????? ? ? ? ? ? FlexNetFs.76491

So, it is suggested to customers to configure their monitoring tool (if any) to ignore any folders matching the name "/dev/shm/FlexNetFs.*"
