It is the first time I see a dnsdist crash.
Unfortunately we do not have any core dump.

Jan 29 22:48:09 kernel: pid 75804 (dnsdist), jid 0, uid 208: exited on signal 11 (no core dump - bad address)

Our dnsdist runs behind an nginx and forwards queries to recursors.

Are there any currently known bugs that could cause this?

I'm not aware of any bug in 1.9.8 that could cause a crash, no. It's hard to narrow it down with the information you have, unfortunately. Did you upgrade recently from a previous version of dnsdist (in which case I can look at the diff since the previous version)? Or perhaps did you change something in the configuration? I don't see anything out of the ordinary in your configuration.

Best regards,
