The file size exceeded the limit specified by ulimit(1), or the file size exceeds the maximum supported by the file system. New data created under this condition can probably be lost.
In the C shell, use the limit(1) command to see or set the default file size. In the Bourne or Korn shells, use the ulimit -a command. Even when the shells claim that the file size is unlimited, in fact the system limit is FCHR_MAX (usually 1 Gbyte).
The symbolic name for this error is EFBIG, errno=27.
