Created attachment 1025409 [details]
/var/tmp/abrt/ directory as a tar archive compressed with xz

Description of problem:

I run `systemctl daemon-reload` after changing /etc/systemd/system/sshd.service.d/local.conf from

[Service]
ExecStart=
ExecStart=/usr/sbin/sshd -D -e

to

[Service]
ExecStart=""
ExecStart=/usr/sbin/sshd -D -e

That resulted in:

[root@dserver ~]# systemctl daemon-reload

Broadcast message from systemd-journald@dserver (Thu 2015-05-14 15:27:39 CEST):

systemd[1]: Caught <ABRT>, dumped core as pid 5583.


Broadcast message from systemd-journald@dserver (Thu 2015-05-14 15:27:39 CEST):

systemd[1]: Freezing execution.

Failed to execute operation: Connection reset by peer
[root@dserver ~]# 

Version-Release number of selected component (if applicable): systemd 219

I experienced the problem only once.

I attach the abort directory with all details, but here is the stack trace from the core dump:
