Hello, André, The fact that the amount of time that Fedora takes to start up is variable suggests to me that ActiveMQ is trying to resend messages it has stuck in its queue. Few messages, quick startup, lots of messages, slow startup. You could verify that by deleting the messages in the queue, shutting down Fedora, starting it back up again, and seeing if it starts immediately; then perform a number of API-M actions (ingests, updates, etc.), examining the state of the queue, shutting down Fedora, starting it up again, and see if it takes a while.
See http://activemq.apache.org/how-do-i-purge-a-queue.html for information on purging a queue. Once you've verified that is, in fact, the problem, then you'll need to see why messages are getting stuck in the queue: perhaps no configured message consumer? -- Scott On 08/10/2012 02:15 PM, André Lapointe wrote: > Hi, > > On Tomcat startup, our fedora installation hangs for a few minutes, > sometimes for as long as an hour.
