Suricata

Setting preserve-order to false could be a workaround.

Bug reported to Ubuntu https://bugs.launchpad.net/ubuntu/+source/jansson/+bug/1785077 (private issue for now)

Suricata would crash when writing out an EVE record. It would get a SIGABRT with a line like:

suricata: dump.c:337: do_dump: Assertion `value' failed.

A backtrace would look like:
