Description Chris Murphy 2015-12-14 20:32:26 UTC 
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):
gnome-terminal-3.18.2-1.fc23.x86_64

How reproducible:
Always


Steps to Reproduce:
1. gnome-terminal, preferences, uncheck limit scrollback option
2. ssh to remote system
3. btrfs-debug-tree -t2 <dev>


Actual results:

Hang, including mouse arrow, then gnome-terminal-server killed by SIGSEGV- abrt.



Expected results:

No crash. If for some reason it can't handled 171MB it should fail more gracefully.

Comment 7 Fedora End Of Life 2016-11-24 14:14:10 UTC 
This message is a reminder that Fedora 23 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 23. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '23'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 23 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.
Comment 8 Fedora End Of Life 2016-12-20 17:01:09 UTC 
Fedora 23 changed to end-of-life (EOL) status on 2016-12-20. Fedora 23 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
