Since the upgrade to 7.6, I have been unable to use unbound in the previous configuration.
root@router ~ # rcctl -df start unbound doing _rc_parse_conf unbound_flags >-c /var/unbound/etc/unbound.conf< doing rc_check unbound doing rc_pre /var/unbound/db/root.key has content success: the anchor is ok /var/unbound/etc/blocklistproject/ads.txt.conf:9973: error: yacc stack overflow read /var/unbound/etc/unbound.conf failed: 1 errors in configuration file doing _rc_rm_runfile (failed) root@router ~ # In this case, I'm using an unboundified version of ads.txt from the blocklist project, https://github.com/blocklistproject/Lists. These files are pretty large, in this case >250k lines. Manual editing to reduce file size is not an option. The error message makes me think that this is not a configurable limit in unbound. Any suggestions how to tackle this?
