Subject ActiveMQ hangs and i don't understand why
Date Sat, 26 Mar 2016 09:27:22 GMT
My problem:
ActiveMQ hangs yesterday, i could not open web-interface, consumers could
not connect to broker.
After restarting ActiveMQ all works well. 
We use ActiveMQ Version 5.10.1. Uptime before this problem was more than 60
days. 60 days ago was last settings changing and we don't have such problems
before.
We use written in php producers and consumers. Some producers and consumers
work with persistence messages, and some with non-persistence (this messages
contains log-info).
Consumers and producers connect to ActiveMQ via stomp protocol implemented
by this library: https://github.com/centraldesktop/php-stomp (By the way,
what is the best tool for producing and consuming messages from php? With
keep-alive and etc?)

And in ActiveMQ logs i see such messages:
