more insight:
after restarting memcache I could list the mount, but then this happened
user@laptop:~$ sudo ls -l /mnt/mc-11212
ls: cannot access /mnt/mc-11212/d0f0e7dc0c93c78f979d24a02ce1dfd9: Transport endpoint is not connected
ls: cannot access /mnt/mc-11212/2ac0070d6ee41fa0e37a9b0221b5f233: Transport endpoint is not connected
ls: cannot access...
When I list the mounted memcached instance I get the following error: "ls: cannot access /mnt/mc-11211: Transport endpoint is not connected"
the memcache instance is 500MB in size.
