[jira] [Created] (AMQ-4853) Advisory support leads to excessive CPU
usage
Joshua Watkins created AMQ-4853:
-----------------------------------
Summary: Advisory support leads to excessive CPU usage
Key: AMQ-4853
URL: https://issues.apache.org/jira/browse/AMQ-4853
Project: ActiveMQ
Issue Type: Bug
Components: Broker
Affects Versions: 5.9.0
Reporter: Joshua Watkins
After upgrading from AMQ 5.8 to 5.9 we have seen cpu usage continually climb until AMQ threads are taking nearly all of the CPU Resources while remaining fairly idle. This is just a single broker with advisory support on. (Advisory support is on in this case as we run the same config for a network of brokers.) Turning off advisory support reduced the CPU load to single digits.
