----------------------------------

             Summary: ActiveMQ client loses connectivity and admin interface is corrupted
after being up for 72 hours
                 Key: AMQ-4872
                 URL: https://issues.apache.org/jira/browse/AMQ-4872
             Project: ActiveMQ
          Issue Type: Bug
    Affects Versions: 5.5.0
         Environment: Centos 6.4. ActiveMQ running at nice 0, several clients running at nice
10 and one running at nice -10.
            Reporter: John Griffith


We run an application that, at the moment, creates and uses three queues accessed via Spring
JMSTemplate: Ingest, IngestRequest, and Index.

ActiveMQ ran fine for a period of about 60 hours. The system came under heavy, continuous
load at about the 55 hour mark. At about the 60 hour point, the high-priority client (using
spring jmsTemplate) lost it's connection to the ActiveMQ server, reporting a jms ConnectionFailedException.
On the server side, ActiveMQ logged the following for each attempt to connect by the client:

bq. 2013-11-11 11:50:12,667 [127.0.0.1:48682] INFO  Transport                      - Transport
failed: java.io.EOFException

In addition, accessing the queues in the web administrative interface shows a list of 'garbage'
entries that includes the list of files that appear to be from a cgi directory, but includes
.asp files that one wouldn't find on a Linux host.

Running 'service activemq status' reports activemq as being up. Clients can not connect to
it, however. There is plenty of disk space and memory available, however there are long-running
(minutes) tasks that could conceivably starve ActiveMQ for CPU time - these tasks all run
at the higher nice value.
