systemd-coredumpctl - broken ?

Confused :

[ root@jvdlin:/tmp 15:53:50 2542:105 ]
$ systemd-coredumpctl list 29588
TIME                                         PID   UID   GID SIG EXE
              Thu 2013-04-11 15:18:17 GMT  29588     0     0  11 /usr/libexec/ftpd
[ root@jvdlin:/tmp 15:53:55 2543:106 ]
$ systemd-coredumpctl -o core.ftpd.29588 dump 29588
TIME                                         PID   UID   GID SIG EXE
              Thu 2013-04-11 15:18:17 GMT  29588     0     0  11 /usr/libexec/ftpd
More than one entry matches, ignoring rest.
[ root@jvdlin:/tmp 15:54:03 2544:107 ]

ie. systemd-coredumpctl lists only one coredump for process 29588 . Why can't it dump this ?
Why does it think there is more than one dump ?

How do you get systemd-coredumpctl  to dump a coredump ?

Is the above behaviour a bug ?  ie. it lists only one coredump but has convinced itself that there is more
than one match ?  Should I raise a bug or am I missing something ? The above command line conforms
to that documented in man systemd-coredumpctl :
    systemd-coredumpctl [OPTIONS...] {COMMAND} [PID|COMM|EXE|MATCH...]
I've also tried:
     $ systemd-coredumpctl -o core.ftpd.29588 dump '29588|ftpd|/usr/libexec/ftpd|libexec/ftpd$'
     $ systemd-coredumpctl -o core.ftpd.29588 dump 'libexec/ftpd$'
     $ systemd-coredumpctl -o core.ftpd.29588 dump 'libexec/ftpd'
     $ systemd-coredumpctl -o core.ftpd.29588 dump '/usr/libexec/ftpd'
with same result as above.

This is on a fully up-to-date ArchLinux x86-64 multilib installation.

please use code tags around snippets to make your post more readable.

Also search the forums for this

warning: config file /etc/pacman.conf, line 19: directive 'SyncFirst' in section 'options' not recognized.

SyncFirst is no longer supported.

Re: systemd-coredumpctl - broken ?

Of course, this issue is nothing to do with the SyncFirst option in pacman.conf, which I've commented out, or pacman.

This issue is only about systemd-coredumpctl , which appears to be unusably broken in the version installed as part of  'pacman -Su' .
I guess my question is answered : it appears not to be a known issue, so I will raise a bug about it.

I will try to use <code> </code> snippets in future - sorry if their omission made my previous post unclear.

You can still edit the post. Also its not the html tags, but BBCode tags like so [code ] [/code ] (without the spaces of course)

and why are you not doing a -Syu ?? its better to update your databases when upgrading packages.

Re: systemd-coredumpctl - broken ?

I'm having the same issue with systemd-coredumpctl & I cannot find any way to delete the core dumps held within journal

Beginning to consider a move as systemd is proving to be a bit too contrived for me & I hear it wants to control sysctl as well!!

Re: systemd-coredumpctl - broken ?

I’ve had trouble accessing my core dumps with systemd too. I have already disabled systemd’s journal after finding that it wasted 680 MB on my disk, but I’m not sure if that disables the hijacking of core dumps. I’ve just searched how to do that and found this answer:

# ln -s /dev/null /etc/sysctl.d/coredump.conf
# /lib/systemd/systemd-sysctl # or possibly a reboot
