Failed to create aux thread - when making a backup

Hello,

I need to migrate our ejabberd version 2.1.12 (Gentoo 32bit) to 64bit Debian.
Trouble is that it fails to make backup of Mnesia database:

# ejabberdctl --node ejabberd@gandalf backup /tmp/aqq

Crash dump was written to: /var/log/jabber/erl_crash_20130722-095452.dump
Failed to create aux thread

Here are contents of that erl_crash - http://paste.ubuntu.com/5899760/

Also I tried to copy database directory directly to new host but it also crashes:

root@frodo:/home/alchemyx# /etc/init.d/ejabberd start
Starting jabber server: ejabberd
Crash dump was written to: /var/log/ejabberd/erl_crash.dump
Kernel pid terminated (application_controller) ({application_start_failure,kernel,{shutdown,{kernel,start,[normal,[]]}}})

Crash dump was written to: /var/log/ejabberd/erl_crash.dump
Kernel pid terminated (application_controller) ({application_start_failure,kernel,{shutdown,{kernel,start,[normal,[]]}}})

Here is erl_crash.dump - http://paste.ubuntu.com/5899764/

Any help will be greatly appreciated. Thank you!
