Subject: gnome-terminal uses excessive memory -- leak suspected

Date: Wed, 31 Oct 2007 23:32:26 -0600

[Message part 1 (text/plain, inline)]

Package: gnome-terminal
Version: 2.18.1-1
Severity: important

I've had gnome-terminal in use for a while with default settings
(scrollback 500 lines or 318kb) and it's using a HUGE amount of memory.
I'm seeint the same from both gnome-panel and galeon so i suspect it
could well be an issue in a library used by all three.  I've looked at
the list for gnome-panel, and this could be related to bug #445340.
Here is it's line from top:
12381 ariana    19   4  458m 368m  13m R  1.0 24.3  12:09.19
gnome-terminal

I am going to also report against galeon and reference this and #445340,
feel free to consolidate if you this they are the same bug.

 Could you check with 2.18.2?  If it still leaks for you, please run
 gnome-terminal in valgrind and see whether you can identify the leak.

at least I've seen it here again... not sure how reproducible it is
though. if I find the time I will do some more investigations.

Subject: gnome-terminal memory management

Date: Wed, 3 Dec 2008 13:02:46 +0000

[Message part 1 (text/plain, inline)]

Hello,

I experience the same memory hogging with gnome-terminal.  In fact, in
my system, long-running gnome-terminals are the applications that use up
the highest amount of memory.

I did set scrollback to large values (50000 lines, 32421Kb), but the
memory used hardly matches that.  The terminal I'm using, with 3 tabs
open, has this memory footprint at the moment:

  VIRT  RES  SHR
  666m  63m  11m

I can go in every tab and type 'reset' to clear the scrollback: it
spends maybe a minute messing through swap, it clears the scrollback,
and it leaves the memory usage unchanged.

I tried to monitor (via ps aux) the memory usage of a terminal with
several tabs open, as I was closing them one by one:

$ ps axuwww|grep 26142 (repeated)

Closing tabs, the memory usage seems to go UP instead of down.

I ran "valgrind --leak-check=full gnome-terminal", then I opened a new
tab, generated some backscroll with a "find /", closed the tab and
closed the terminal.  Please find attached the results, this is the
summary:

==24563== LEAK SUMMARY:
==24563==    definitely lost: 37,962 bytes in 66 blocks.
==24563==    indirectly lost: 110,480 bytes in 3,455 blocks.
==24563==      possibly lost: 170,000 bytes in 145 blocks.
==24563==    still reachable: 63,587,633 bytes in 91,734 blocks.
==24563==         suppressed: 0 bytes in 0 blocks.
 

Ciao,

Enrico

Could you please try again with gnome-terminal 2.24 which lies in
experimental? This is a full rewrite and it seems to use less memory
than that.

Thanks,

Hey,

Could you please try to reproduce this issue with newer version
like 3.10.1-1 ?
