Subject Re: ActiveMQ threads clogging CPU
Date Tue, 18 Apr 2017 08:30:19 GMT
Hi Tim,

Thank you for replying.

Yes we have intermittent network connection, as our app runs on a vehicle
which is travelling. We observed this issue when our app runs on a vehicle
which looses connection. On one particular instance it looses connection for
6 hours continously.

Regardless of whether it is connected or disconnected we are observing this
issue after few hours. For one vehicle we see its occurs after 3 hours and
on some after 6 hours. We see 20% CPU utilization when app is started and
when it is 100 or more we see 228 threads for ActiveMQ Task out of total 460
threads in jvm. And thread name that start with ActiveMQ are 272. Also
attaching .txt for ActiveMQ Task and Transport thread stack trace. We see
ActiveMQ Task mostly in waiting state.

Please let me know if i am not clear.

Thank You,
Dheeraj activemq.txt
