[Pdns-users] pdns backend connection drops

[Medovárszky Zoltán]

Dear Community,

I'm having a serious problem for a few days now.

I have a powerdns superslave configuration with 2000 domain names, with
approx. 20.000 records.
The pdns server logs the folowwing errors and this problem repeats in
every 2-3 minutes.

It started with 2.9.20 debian package. Now I've upgraded to 2.9.21 from
source, the problem persists.

Mysql has enough available connections.

Any suggestion is welcome.

Zoltan
