@ Achelne : seems like it.

This is what i get when running it as root, which expected to have the rights to actualy create a core dump, but it didnt neither Smilie
Code:
...
/root/.cache/vhs.tmp: line 1: 16723 Floating point exception(core dumped) vobcopy -o "/root/.cache/Avatar" 2> "/root/.cache/vhs.tmp.vobcopy"
# | Creating tempdata, this may take a while...                                       ( 917M )                                               [  /   ] | #^C

130 /home/sea/.local/bin # cat /root/.cache/vhs.tmp
cat  /root/.cache/Avatar/AVATAR1-1.vob /root/.cache/Avatar/AVATAR1-2.vob.partial > "/root/.cache/Avatar/BIGVOB.vob"

+ /home/sea/.local/bin # coredumpctl 
No coredumps found.

Guess i'll have to file a bug and accept for the moment that vobcopy doesnt run well in background Smilie

Note that it wouldn't literally be core.pid, it would be core.ProcessIDOfProgramThatDroppedCore (which in this case would be core.20608).

It looks like /var/lib/systemd/coredump is used when your system crashes (not when user processes running on your system crash). On most systems I've used, a core file would be placed in the directory that:
  • was the current working directory of the process when it died,
  • was the current working directory of the process when it started,
  • was the home directory of the user who started the process, or
  • was a subdirectory of the home directory of the user who started the process.

The diagnostic you received from bash:
Code:
/home/sea/.local/bin/vhs.sh: line 658: 20608 Floating point exception(core dumped) vobcopy -o "$1" 2> "$vTMP"

indicates that bash was told that a core file was produced. But, obviously, configuration parameters can disable core file production.

If locate core and core.20608 don't find anything, we have to assume that your system didn't drop a core or some cron job removed it before you looked for it.

Hope this helps...

Sadly, the change of the literal 'pid' to its PID didnt bring up any locate result.
That was right now after it failed again, on yet another dvd... guess i got to live with the regular console output of vobcopy...

Code:
# | pid:4929                          Copying: SCARFACE1-2.vob (129M)                                  [  -   ] | #
/home/sea/.cache/vhs.tmp: Zeile 1:  4931 Gleitkomma-Ausnahme     (Speicherabzug geschrieben) vobcopy -o "/home/sea/.cache/Scarface" > /dev/zero 2> "/home/sea/.cache/vhs.tmp.vobcopy"
# | Created tempdata                                                                                   [  √   ] | #
# | Press 'CTRL+C' to stop encoding from dvd...                                                        [ ⚠ⅈ⚠  ] | #
# | Saving to '/home/sea/dvd-Scarface.0.mkv'                              ( 50M )                      [  \   ] | #^C
130 ~ $ locate core.4931
:( ~ $ sudo locate core.4931
- ~ $ sudo locate core.4929

And still no coredumpctl output either Smilie
And without that information, one cannot solve the issue, so, thank you so far! Smilie

Happy holidays Smilie
