Could not drop root uid

[Christian Klossek]

Hi,

I'm using maradns 1.3.07.09 on a mail-server with Debian Lenny.
My mararc looks like this:
--------------------------------------
ipv4_bind_addresses = "127.0.0.1"
chroot_dir = "/etc/maradns"
recursive_acl = "127.0.0.1"
maximum_cache_elements = 70000
--------------------------------------

Sometimes, when there are a lot of incoming/outgoing mails, maradns is
not responding anymore. When I close it and try to start it manually I
get the following error-message:

Fatal error: Could not drop root uid

After that maradns is closed.
What can I do?

If you need more information about the system, don't hesitate to ask.

Best regards
