That sounds like a file system problem, for example that the connection
from the machine that tries to open the file to the NFS server times out
(maybe because the file server is overloaded with requests from other
machines). That's something you need to talk to your system
administrator about.
Or it may be a race condition -- for example if you try to open the same
file from multiple MPI processes at the same time (which you shouldn't
do anyway!).
