Hi Robbie,
We are trying to replicate this issue from our end, so we can confidently
apply fix and roll out to all. We need some your input/help to replicate
this issue. It could be be some issue from my end, So I am trying to find
trouble code as well. Sorry for many questions.
In May, we had this issue due to bad Message which was published with .Net,
but now we got issue due to normal messages as well.
We are having this issue while restarting of ServiceBus connector restart
(due to ServiceBus connectivity loss). I follow below steps for restart -
-------------------------------------------
1. Closing and Nullifying JMS Objects
a. Connection.close(),
Connection = null,
b. MessageConsumer.setMessageListener(null); --> I think i am doing wrong
here. I don't need to set null here, as i am closing on next step. What's
your opinion?
MessageConsumer.close();
MessageConsumer=null;
c. Session.close();
Session = null
------------------------------------------
2. Creating JMS Objects
a. Create Connection
b. Create Session
c. Create Consumer
------------------------------------------
Q1. ) Could you please suggest if I am doing anything wrong while restarting
of JMS Objects ?
Q2. ) If we got any exception while closing Connection, Session, Consumer
and Producer, then how can we make sure that Connection, Session, Consumer
and Producer closed and clear successfully from system?
Is it good practise set Null to JMS Objects after closing to make sure that
JMS Objects are cleaned up properly?
I want to make sure that JMS object and threads are clear from system
properly before creating new connection, so it will not cause any issue
while starting of JMS connection, Session, etc.
Overall I feel that, this could be an issue with clearance/disposing of
existing JMS Objects.
Could you please suggest your opinion to handle gracefully for exception
scenario while closing JMS Objects?
Q3. ) We got "Illegal invocation from MessageListener callback" error while
closing Connection & Session, and then we started having "Suspected
deadlocked threads" error.
Could you please suggest any idea to generate "Illegal invocation from
MessageListener callback" error ? It could be one of reason for deadlocked.
If I am able to generate this error then I could generate deadlock error.
It will be great help if you provide your opinion on above queries.
Please find below error logs.
