vv_flush : I/O error 5 on fd1
What is a vv_flush?
In 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.
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.
1- 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.
2- In Version 7.2, and 7.3Axx, there was a bug that caused a runaway
process when an _progres process did not get a HANGUP SIGNAL. This
bug is fixed in Version 7.3Cxx.
