Nope, unfortunately, I don't. Am I right that I should also read

$ ls -la /var/crash
drwxr-x--- 2 root wheel 3 Jul 11 2014 .
drwxr-xr-x 24 root wheel 24 Sep 2 12:23 ..

$ cat /var/crash/minfree
Does this mean that it wasn't a kernel panic at all? Or isn't there
something worth noticing because I don't have dumpdev configured?
I'm afraid that I can't remember another change that I made to the jail
that caused it to crash. But, up to now, the only thing I can remember I
did was upgrading net/syncthing.

I definitely want to further investigate the problem and keep everyone
updated about it. It's just that I need some help to do that, so your
reply is very much appreciated. I'm definitely not a free rider. ;-)
So far, I haven't started the jail again since it has continuously
broken my system. (I'm scared.) I will configure dumpdev first and after
that I'll start the jail. I'll keep you updated.
