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,
