This should not happen, of course.  If you have a system error reporting
facility (I don't know Solaris), that would be one place to check for
an explanation.

The only thing I can guess your program could do is "try again".  I would
be tempted to get away from the file object I/O, because it's implemented
on C stdio and inherits problems typical of C software.  But that's long
odds, and probably not worth it if the input is going to be line oriented
or otherwise unsuitable for posix I/O.
