Public bug reported: Steps to reproduce:
1) Open gnome-terminal with bash shell. 2) type tail -f someLogFile 3) Let it run with plenty of output for a long time. Result: Tail output will suddenly stop. Stracing the bash process shows: mm@musca:~ $ sudo strace -p 31412 [sudo] password for mm: Process 31412 attached - interrupt to quit wait4(-1, Stracing the tail process shows: sudo strace -p 17298 [sudo] password for mm: Process 17298 attached - interrupt to quit write(1, "ull;null;null;null;0;null;eurex;"..., 4515^C <unfinished ...> Process 17298 detached It seems that the processes are somehow deadlocked. After killing the tail process, the tail died, but the gnome-terminal stayed unusable. mm@musca:~ $ sudo strace -p 31412 [sudo] password for mm: Process 31412 attached - interrupt to quit wait4(-1, [{WIFSIGNALED(s) && WTERMSIG(s) == SIGTERM}], WSTOPPED|WCONTINUED, NULL) = 17298 rt_sigprocmask(SIG_BLOCK, [CHLD TSTP TTIN TTOU], [CHLD], 8) = 0 ioctl(255, TIOCSPGRP, [31412]) = 0 rt_sigprocmask(SIG_SETMASK, [CHLD], NULL, 8) = 0 ioctl(255, SNDCTL_TMR_TIMEBASE or TCGETS, {B38400 opost isig icanon echo ...}) = 0 ioctl(255, SNDCTL_TMR_STOP or TCSETSW, {B38400 opost isig icanon echo ...}) = 0 ioctl(255, SNDCTL_TMR_TIMEBASE or TCGETS, {B38400 opost isig icanon echo ...}) = 0 ioctl(255, TIOCGWINSZ, {ws_row=63, ws_col=211, ws_xpixel=0, ws_ypixel=0}) = 0 write(2, "Terminated\n", 11 Choosing "Terminal->Reset" from gnome-terminal menu did not help. Choosing "Terminal->Reset And Clear" from gnome-terminal menu made the window usable again.. Probably there is a problem with a buffer overflow, etc. I am using a scrollback of 1000000 lines. The output should have been sufficient to fill this buffer.
