Importing users from jabberd

Hi everyone!

We have a Jabberd Version: 1.4.3-3 installed in Ubuntu 8.04 box and we are migrating to ejabberd Version: 2.0.1-2~hardy1 over a similar box.

The issues appears when importing the two thousands users to the new ejabberd server.

after installing the server, using dpkg-reconfigure, the node and admin user are created succefully such that we can access the admin web interface without problems.

Following the instructions found on
http://www.ejabberd.im/jabberd1-to-ejabberd

we exectute ejabberdctl --node ejabberd@server import-dir PATH_TO_SPOOL_directory_of_the_jabberd_server

after that, things start ok but when reaching 600 aprox users imported, the server crashes saying: RPC failed: nodedown

and when trying to start the server

ejabberdctl start
RPC failed on the node ejabberd@server: {'EXIT',
{badarg,
[{ets,
lookup,
[hooks,
{ejabberd_ctl_process,global}]},
{ejabberd_hooks,run_fold,4},
{ejabberd_ctl,process,1},
{rpc,'-handle_call/3-fun-0-',5}]}}

The above only can be solved by reinstalling and purging all the conf files.
We changed the log level to debug and the following appears during the import process:

the later was for every imported user.

Also, we have found that the server runs out of free kernel buffers during the import process.

Any suggestions???

Thanks in advance,
