Server crash on creating new users

Hi Guys, insalled the system for the very 1st time. Started adding users, then the system crashes.

the following is displayed on the control panel (any ideas of the cause?):.

Hi,

it will help a lot to avoid using “_” in your JID.

LG

ok, thank you I will bear this in mind.

Thanks
