Hi: I seem to be hitting my maximum pty limit after running my cygwin machine for about a week. I open rxvt terminals and have an openssh server. rxvt on the machine and connections via ssh work fine after reboot. After about 1 week goes by I get messages about failure to allocate a pty.
Once this happens, I can't open an rxvt at the machine anymore (get error message: can't open pseudo-tty), or ssh in (get error message: PTY allocation request failed on channel 0). If I shut down an existing rxvt window on my machine, I can create one more rxvt (or connect via ssh one more time), but then I hit the limit again (get the failure messages) when I try to open another one. I don't have many windows open, but I think ptys may not be getting freed when ssh connections shut down in a not so nice way. In cygwin, how do I determine how many ptys are in use? How do I determine which processes are using a pty? I found the following link with Google, but the procedure does not work for cygwin: http://www.cyberciti.biz/tips/howto-linux-increase-pty-session.html I run an openssh server, and sometimes the clients may shut down in a not so nice way (due to lid closing on laptop client). Maybe the ptys are not getting freed when this happens? I've tried searching this mailing list and could not find any emails about this issue. If they do exist, please send me the links with the answers. I'm using Windows 7, and uname -a shows: CYGWIN_NT-6.1-WOW64 rob-server 1.7.6(0.230/5/3) 2010-08-16 16:06 i686 Cygwin Please help.
