[Pdns-users] 5001 questions waiting for database attention. Limit is 5000, respawning

[Stan Weatherby]

Hello,

We are experiencing a very strange issue. Our PDNSD servers keep getting the error: 5001 questions waiting for database attention. Limit is 5000, respawning which is killing the answer side.

Here is the strange thing, we are not using the MySQL backend, we are using the pipe backend and running heavy cache. In the config file we do not ask to load MySQL just “pipe”, has anyone else experienced this issue? We see this happen on loads of about 50 requests per second CPU - RAM - and all other system resources are running at a nominal load.

Maybe we are missing some performance tuning? Still wondering why PDNSD is looking for the DB.
