[Linux] IDE crashes one time a day

[Kiiv]

Hi,

At least since 2022-12 update, Eclipse crashes few minutes after the first launch of the day.
I know it's kinda weird but after I relaunch it, I have no more problem for the rest of the day :s

I'm just launching my IDE, start to work, and after some random time but not more than an hour, the IDE is closing itself.
hs_err_pid228593.log
metadata.log

Tell me if you need more log.

Regards,
Clément.

[mickaelistria]

Can you please share information about the Linux distribution you're using and version of gtk and family?

[iloveeclipse]

This could be either Ubuntu specific GTK problem, or Wayland you are using.
Try to use X11 please.

[akurtakov]

The issue is in Pango integration (pango_attr_list_unref) and SWT hasn't been updated to latest Pango changes so I highly doubt this is WM related issue.

[akurtakov]

One known pango integration issue is #411 . @Kiiv would you please share your libpango version?

[akurtakov]

Interesting, this is far older pango than I expected (although 1.44 is where our issues started) . This makes me think in another direction - Do you by any chance changed the Gtk theme used? Can you try whether switching to Adwaita keeps the issue present?

[Kiiv]

Sorry if my response is not the expected one, I'm really not a Linux expert.

As graphic environnement I'm running xfce or KDE Plasma Desktop and I encounter the problem with both.
Can't check with KDE Plasma for now, but I don't think I have any theme applied on xfce. I don't even have anything else than adwaita-icon installed :

$ sudo dpkg -l | grep adwaita
ii  adwaita-icon-theme                            3.36.1-2ubuntu0.20.04.2                     all          default icon theme of GNOME (small subset)
ii  adwaita-icon-theme-full                       3.36.1-2ubuntu0.20.04.2                     all          default icon theme of GNOME

[akurtakov]

Verify you actually use adwaita gtk theme for an experiment as described at https://www.omgubuntu.co.uk/2019/04/how-to-try-the-new-adwaita-theme-on-ubuntu-19-04

[Kiiv]

Ok, I'm on Breeze theme ! I'm switching to Adwaita and I'll keep you up to date.

[Kiiv]

Ok, that was fast :')

hs_err_pid253251.log
metadata.log

[akurtakov]

Unfortunately, I can't find anything helpful in the log.

[SyntevoAlex]

The code mentioned in callstack is executed whenever editing caret moves to a new line is source code editor.
I tried it under memory debugger, but it didn't catch any problems.

[Kiiv]

Can I do something on my side to investigate further ? Enable some debug trace, or run a tool to get more information when it happens ?

[SyntevoAlex]

Let's capture a core dump to investigate further.

Note that this core dump will contain everything Eclipse knew at the moment of crash, including parts of source files, passwords, etc. If you're working on something private, you might want to create an empty workspace and reproduce the crash on some opensource code.

If you don't know how to reproduce crash quickly, you might want to install OBS-Studio and record your screen during your working days. When it crashes, check what exactly you did just before the crash and try to repeat it with exactly same source file / line.

1. Enable core dumps on your system:
   $ ulimit -c unlimited
2. Enable core dumps in Eclipse:
   Add -XX:+CreateCoredumpOnCrash in eclipse.ini
3. Start Eclipse from terminal
4. When it crashes, you'll see lines like this on terminal:

   # Core dump will be written. Default location: Core dumps may be processed with
     "/usr/share/apport/apport -p%p -s%s -c%c -d%d -P%P -u%u -g%g -- %E"
     (or dumping to /home/user/core.4448)
   #
   # An error report file with more information is saved as:
   # /home/user/hs_err_pid4448.log
   
   

5. Find core dump (check or dumping to in message above)
6. Compress it, preferably with 7-zip (works much better than zip on core dumps).
7. Share the file with me.

Hi,

don't know if this is the same problem as usual but got this when it happend today :

***MEMORY-ERROR***: Eclipse[3633]: GSlice: assertion failed: sinfo->n_allocated > 0

No core dump written. But it's strange I don't have any hs_err_pid file either.

[Kiiv]

This one is referenced here :
https://bugs.eclipse.org/bugs/show_bug.cgi?id=538000
https://gitlab.gnome.org/GNOME/gtk/-/issues/210

But no one tell about a total crash of Eclipse.

[iloveeclipse]

assertion 'size >= 0' failed in GtkScrollbar is irrelevant here, it spams Eclipse logs since ever without any crashes.

What crashes JVM is GSlice: assertion failed: sinfo->n_allocated > 0.

Similar crash was reported in other applications too, like

• https://bugzilla.redhat.com/show_bug.cgi?id=1830428
• https://unix.stackexchange.com/questions/281523/tshark-memory-error-6265-gslice-assertion-failed-sinfo-n-allocate
• http://technostuff.blogspot.com/2019/03/debugging-issues-related-to-glib.html

The last link gives some hints, feel free to try them out, I'm not familiar with this code & haven't seen such crashes yet.

[SyntevoAlex]

Did you have any crashes (with hs_err_pid files) since you enabled -XX:+CreateCoredumpOnCrash ?

[Kiiv]

Hi !

got this one today :)
hs_err_pid127091_core_dump_enabled.log

Unfortunately I don't find any core dump at the specified location :s

[Kiiv]

Most of the time, it crashes whith only this message :
"MEMORY-ERROR: Eclipse[204252]: GSlice: assertion failed: sinfo->n_allocated > 0"

No pid log file or core dump...

[SyntevoAlex]

It seems that something is corrupting memory in Eclipse, which manifests as various random crashes.

I guess we'll have to resort to memory verifier, now that attempts to catch a core dump didn't succeed.

Please do the following to build it:

1. sudo apt install build-essential scons
2. git clone https://github.com/SyntevoAlex/ElectricFence ~/Downloads/ElectricFence
3. cd ~/Downloads/ElectricFence
4. scons

Then, run Eclipse this way:

1. sudo sysctl -w vm.max_map_count=1000000000
2. G_SLICE=always-malloc EF_ALIGNMENT=16 EF_ALLOW_MALLOC_0=1 LD_PRELOAD=~/Downloads/ElectricFence/src/libefence.so ~/Downloads/eclipse/eclipse

If you do it correctly, you should see additional headers printed to console when running Eclipse.
Eclipse will be significantly slower (expect some 30 secs just to start it), but all memory access will be tested thoroughly.
Try using it for a couple minutes; I expect that it will crash and finally produce better crash logs pointing to the guilty code.

[Kiiv]

Ok I'll try that. Does this can expose sensitive data I'm working on or it will only record technical information ?

[SyntevoAlex]

The core dump will contain everything that Eclipse had in memory, which could contain various sensitive information. The hs_err_pid.log file is much less likely to contain anything sensitive. I hope that the new hs_err_pid.log will be more useful.
