By "stops working", do you mean that the process dies or it just stops responding or it only sends out SERVFAILs?

This is the `basic-query`, interesting that it gives this error, as we never bind more than 2 elements in the code.

If your server is not stressed for resources could you set `query-logging=yes` in the pdns.conf (with possibly `loglevel=7` as well if no queries show up in syslog) to identify the query that causes this and share the results with us?

Secondly, could you share your pdns.conf (without passwords)?
