eDir core when stopping DCS driver

[alekz]

Hello,

Had something odd happen today, I was import a LDIF file containing
about 1 million users, it was at about 780 000 when I decided I wanted
to stop the DCS driver because the Reporting database was having some
issues.

When I clicked Stop, eDirectory stopped responding.

No core file was created even though the hs_err_pid file tells me it
should be here:
/var/opt/novell/eDirectory/data/dib/core or core.2145

This is SLES12SP3 with IDM 4.7.1.

ulimit reports unlimited

I would really like a core file next time, what can I do?

This is from the hs_err_pid file:

Just restarted eDir, DCS is set to autostart so I clicked Stop once again.
It crashed.

I can see the following process when running top indicating that some
kind of coredump is being created:

/usr/lib/systemd/systemd-coredump 16943 0 0 6 1541268195

Hi Alekz,
How many servers you have in your tree?
I just imported a million objects. Maybe you have a huge sync traffic?

What about consumed memory?

Be sure you have gone over the systemd bits here:

Anything interesting in /var/lib/systemd/coredump/ ?
