SYMPTOM(s):
vv_flush : I/O error 5 on fd1
What is a vv_flush?
CAUSE:
What is a vv_flush?
From Version 7, the PROGRESS terminal interface changed.
The version 6 interface was replaced with Vermont Views, a third party software package. This vv_flush error is generated by the Vermont Views code.
FIX:
What does it mean?
The vv_flush:I/O error 5 on fd1 error means that a message was sent to the tty device, but the PROGRESS client was no longer attached to the tty. The fd1 refers to file descriptor 1, or standard out.
In Version 6, the same situation was reported with this message.
SYSTEM ERROR: I/O error 0 in writeit, ret 0, file(tty), addr <n>.(290)
Should I be concerned about this error?
The vv_flush error by itself is harmless. It is only a symptom of what might be another problem. You might want to analyze why you see this error if it occurs frequently.
Reasons why I might see this error.
The user shut the terminal off and their _progres process never received a HANGUP SIGNAL. This is often the case with users who telnet to the UNIX machine through a PC software emulation package.
