Just a warning for anyone thinking of picking up Erlang programming. The Mnesia database is unstable under 10.04 -- so unstable that it loses the entire database every few restarts of an application.
Do you have any references for this? I have used Mnesia on Ubuntu 10.04 and I haven't lost any data yet. However, I am about to use this combination on a mission-critical system so I really need to know if there is a problem.
