Re: [luciddb-users] org.eigenbase.util.EigenbaseException

[John V. S. <js...@gm...>]

This error occurs if you have two LucidDB processes trying to run from 
the same installation, like if you run lucidDbServer twice at the same 
time from two different shells.  LucidDB locks the catalog exclusively 
when it starts up in order to prevent that.

Use the ps command to find running Java processes.
