This bug has been closed, but I see this behavior quite often:
https://savannah.gnu.org/bugs/?15354
I am running "Screen version 4.00.03 (FAU) 23-Oct-06" on Debian etch. I connect using ssh (specifically putty) to long-running screen sessions (other reports I have found indicate this is significant).
A couple of times a day I see a screen window temporarily freeze. It will be just one window within the screen session, I can still create new windows, switch between screen windows, and work in other screen windows. Usually the frozen window will eventually recover. I am not sure how long it takes to recover, but it appears to be many minutes, maybe 5 or 10 or even 20.
Once the frozen window recovers any keystrokes I entered into the frozen window will appear and everything will be normal again.
If I attempt to kill the frozen window using the 'K' window kill feature screen becomes highly unstable and crashes. If I do nothing in some cases screen will still crash, but this is quite rare. Generally it will recover without any other issue if I wait for a very long time.
What could I do to assist in debugging this? Is there some logging I could enable, or other information I could collect, which would help screen developers to figure this one out?
I can see that it has been reported before by others but that the screen development team has not been able to replicate the issue. I am willing to help out if there is something I could do to help resolve the issue.
