Problem with cyradm

[Sergey Aleshin]

Hello!
I have installed cyrus imap 2.0.12 on my machine. Few days ago machine name
has changed.
And i dont't change secrets for mail administrator in sasldb (it's
important). When i've tried add
a new user  with cyradm, it asks my password and then locks up. Perl process
eats all of
available memory and makes machine unusable. I was able to reproduce it
after reboot. After changing secrets n sasldb all seems to be Ok.So i think
this is a bug in cyradm.
