I don't have it under FreeBSD, but want to share a tip.
Sometimes, dealing with obscure application problem,
I run run an application under "ktrace -i" command to reproduce a problem then exit application.
Then run "kdump | less" and investigate it. There are cases when application generates some error log/report/message
and writes it to its child/parent/sibling over pipe/socket but the message ends up to nowhere.

ktrace shows it, among with other data that may provide a clue.
