Red Hat Bugzilla – Bug 1291417
terminal crashes when scrollback is significant (171MB) and prefs do not limit scrollback
Last modified: 2016-12-20 12:01:09 EST
Description of problem:
GNOME Terminal is configured to not limit scrollback. During remote connection to troubleshoot a file system, the results require a lot of scrollback capacity, i.e. if that scrollback were saved to a file it'd be 171MB. The client running Terminal has 8GiB RAM with the overwhelming majority of it free. But at a certain point during receipt of this stream, Terminal becomes unresponsible and then even the mouse arrow can't be moved and it appears as a fully hung system. But eventually gnome-terminal-server crashes.
The resulting coredump is too big for retrace server, 4.3GB. And gnome-abrt reports it can't find packages for 2 debuginfo files, so it can't file the bug.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. gnome-terminal, preferences, uncheck limit scrollback option
2. ssh to remote system
3. btrfs-debug-tree -t2 <dev>
Hang, including mouse arrow, then gnome-terminal-server killed by SIGSEGV- abrt.
No crash. If for some reason it can't handled 171MB it should fail more gracefully.
