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)?

Best regards,

Pieter
