I am also seeing these. I understand that you can set a thrreshold to stop it logging, but it seems that things slow down or stall while KahaDB performs an index. Ie- consumers of this broker are blocked waiting for the index to complete.
This happens when my message store grows to several thousand messages. Are there any resources or docs on tuning KahaDB? Can I get it to index less often, perhaps. The underlying filesystem is a NAS and I'm using nfs4 with a shared disk HA setup. I doubled the heap space for AMQ (1024M) and it improved for a while. Any thoughts would be appreciated as I can't find any docs on KahaDB. -- View this message in context: http://old.nabble.com/How-to-avoid-%22Slow-KahaDB-access%3A-cleanup-took-545%22-error-msg--tp27158155p27182929.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
