[Pdns-users] stability problem.

[Bart Verbeek]

Hi all,

I've got a stability problem with powerdns version 2.9.13.

First I will tell you my configuration.

I'm running powerdns on a windows 2000 enviroment, with the data stored in a SQL database.
I've created the table using the SQL queries described in SQLlite, and after that I manually changed the ID part of the tables to autonumber.

for testing I created a single zone with around 1000 records for a single domain.
for this I used zone2sql with the --gmysql output.

the sql query created by this program runs fine. and my table is filled without errors.

the SQL database will be connected through ODBC.
everything runs fine.

but now, if I start nslookup on my win2k workstation, and take the following steps;

>server {ip adres of my test server} 
>ls testdomain.ext

Ok this still works fine, and my list will be returned

then directly after I received the whole list (1000 records) I reenter the command
 >ls testdomain.ext
sometimes it works, but sometimes the testserver becomes irresponsive causing NSLOOKUP to have a fatal exception error.
if the second time doesn't end up in failure, it will do the third time.

if I look at the output on the screen it looks like this:

---

the last three errors are displayed if I reconnect with a new NSLOOKUP session. after 3 lookups the pdns.exe just quits.

in a way it seems that the odbc connection backed up. so no more connections are allowed.

Somebody any suggestions?
