Thanks for the link. The Ctl sequences do not seem to be an issue, I have tried several and they seem fine (but not for the freeze problem).I do notice that sending SIGHUP to screen does fix it (at least the terminal, but maybe not the process that was writing to the terminal), though I have also lost the screen session doing that. I need to try more times, and as I mentioned it's an intermittent problem, though it is frequent enough to know it will happen a few times.
Thanks,EdmondOn Thu, Aug 29, 2013 at 5:54 PM, wes <address@hidden> wrote:

I am running gnu screen version 4.00.02.
Everyone once in a while (but consistently) a terminal will freeze
up while printing output and there is no way that I know of to
unfreeze it.
CTL A q does not help and I tried about every command available in
the help.
I can create other terminals within the screen, but cannot usually
reconnect to the screen session it if I detach it. The frozen
terminal remains just that (frozen) until I terminate the entire
screen session.
I also tried the "wipe" function of the screen command, though I
have not seen a need for it.
Any clue what might be happening?

btw, you do not mention trying...
ctrl-a ctrl-q
...and perhaps that is because ^q is not mapped to xon in your
installation. but if it is, you might want to give that a try. (ftr,
i am using version 4.01.00devel (GNU) 2-May-06 in debian 7.1.)
i make the suggestion because on my installation "ctrl-a ctrl-q"
behaves differently than "ctrl-a q". namely, the former happens to
work and the latter does not appear to work (both in a vt and in
xterm). this is despite the fact that my screen installation's help
command informs me that both ^Q and q are mapped to xon.
i have been assuming the discrepancy is most likely due to some
non-screen part of my environment. because i like screen's help
command, and i like to think it would not tell me dirty, dirty lies.
hth,
wes
