Ok, lets try

chmod 777 /var/tmp//fsmem.mpkey
ls -l /var/tmp//fsmem.mpkey

And take a note of the results.

Now we will try fixing the file system first with this command.

fsfix

It will take a while to run. Again take a note of any errors, and reboot when finished then try a daily call.

We will come back to mfscheck next.
