I did further testing. I am using Amazon Linux, "Amazon Linux AMI release 2015.09". In this OS, this issue occurs. Now I tried RHEL 7.1, and this issue didn't occur. In Amazon Linux, this issue even occurs in only one client subscribing the topic.
Another different point: In RHEL 7.1, Apollo is installed with root user. In Amazon Linux, generic user is used, which is the same user as client program runs. Any idea to solve this issue? -- View this message in context: http://activemq.2283324.n4.nabble.com/Apache-Apollo-stop-receiving-messages-until-restarting-the-Apollo-broker-tp4707644p4707645.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
