Hi,

After I rebooted the system due to crash, maddash is broken and won¹t
start.
Here is the information in maddash-server.out²


log4j:WARN No appenders could be found for logger
(com.mchange.v2.resourcepool.B
asicResourcePool).
log4j:WARN Please initialize the log4j system properly.
Initialization error: Connections could not be acquired from the

Any suggestion?

Thanks,
