Sounds like an NFS-mounted file system that was mounted with the hard 
option (or, not explicitly mounted with the soft option--as hard is the 
default).

I'm not suggesting changing this (as there's good reason to use hard 
mounts), but simply saying what you see is exactly what would happen in 
that case, and there's really nothing Myth could do about it.

See man 5 nfs

soft / hard    Determines the recovery behavior of the NFS client after
               an NFS request times out.  If neither option  is  speci-
               fied  (or if the hard option is specified), NFS requests
               are retried indefinitely.  If the soft option is  speci-
               fied,  then  the  NFS  client fails an NFS request after
               retrans retransmissions have been sent, causing the  NFS
               client to return an error to the calling application.

               NB:  A  so-called  "soft"  timeout can cause silent data
               corruption in certain  cases.  As  such,  use  the  soft
               option only when client responsiveness is more important
               than data integrity.  Using NFS over TCP  or  increasing
               the value of the retrans option may mitigate some of the
               risks of using the soft option.
