ELSERVER.COMUsing PowerDNS with a pipe backend causes powerdns to hang when 
system is under load.

Using the sample.pl backend with


causes pdns to loose communication with the pipebackend after a random 
amount of queries when these are performend on parallel. Communication 
between the processes is lost and a BROKEN PIPE error appears.

Has anyone got a similar problem with pipe backends ?

What is the max queries per second you have, in your experience, squized out 
of powerdns with a pipe backend ?
