Hello,

I found a lot of info message in ibmdi.log, it complain about KahaDB, sample as below.

I believe these are normal message for activemq when the logger level is set to INFO.
Here's what I have in <SolutionDirectory>/etc/log4j.properties. You might try these to see if it controls the logging better for you, in regards to activemq

log4j.logger.org.apache.wink=ERROR, Default
log4j.logger.org.apache.activemq=WARN
log4j.logger.org.apache.activemq.spring=WARN
log4j.logger.org.apache.activemq.web.handler=WARN
log4j.logger.org.springframework=WARN
log4j.logger.org.apache.xbean=WARN
log4j.logger.org.apache.camel=ERROR
