I have an issue where my Putty Session will become unresponsive after a period of time. If I am tailing something, or waiting on a process that does not return data while executing, the terminal will lock freeze, even if data then gets returned. Pressing keys will result in a substantial delay until the display suddenly updates and shows the output that was happening in the background.
This is not a CTRL+S issue, this happens without the terminal in focus, and seemingly randomly.
My current workaround is having a clock shell script outputting the time in a corner of the terminal, but this merely allows me to glance and tell if the window is locked, and how long it has been locked. This doesn't work as it moves the cursor, and causes headaches when a lot of data is outputting, or when trying to type.
Is this a server configuration? Or something I should look into with the Putty Client? This only happens on one server that I can tell, so I am not sure. Are there solutions?
