SYMPTOM(s):
UNIX
vv_flush:I/O error 5 on fd 1
CAUSE:
The vv_flush:I/O error 5 on fd 1 error means that a message was sent to the TTY device, however the Progress client was no longer attached to the TTY. "fd 1" refers to file descriptor 1, or standard output.
The vv_flush error by itself is harmless; it is merely the symptom of what might be another problem.
FIX:
To avoid the vv_flush error, you must identify why the TTY device is no longer reachable.
Example: the error is seen when a user shuts the terminal off and their _progres process never receives a HANGUP SIGNAL. This is often the case with users who telnet to the UNIX machine through a PC software emulation package.
