Congrats on getting ActiveMQ into production! That warning, although it's not clear from the message, indicates that the store limit is too high for the amount of space available on the disk and won't prevent running out of disk space -- at least, if I'm reading the code correctly.
if ((storeLimit - storeSize) > dirFreeSpace) { So, either free up disk space from other sources (not ActiveMQ data files) or decrease the store limit in order for it to be effective. Never remove kahadb files unless you want to wipe all of the messages, in which case, wipe the entire directory - while the broker is down. -- View this message in context: http://activemq.2283324.n4.nabble.com/Kahadb-Getting-Worried-Message-tp4679825p4679839.html Sent from the ActiveMQ - Dev mailing list archive at Nabble.com.
