I was having the same issue. Based on what I was seeing I tried to setting
connection parameters based on this documentation
http://activemq.apache.org/tcp-transport-reference.html it did not work.
Following the recommendations here, my problem is solved.
I had updated to HEAD and tried that first before using the
transport.requesttimeout parameter. HEAD by itself did not solve the
problem. However, I don't know if using transport.requesttimeout solved the
problem without the code changes.
What I did find while trying to figure out the problem, is:
- debugging through the NMS code caused the problem to go away.
- it was only reproducible when I ran the produce.Send method.
- not all of the connection parameters are documented, thus making the
choice of configuration changes very limited.
To summarize my issue:
- I have a producer that was working fine until the connection was lost
- if the connection was down and I tried to send from the producer the
thread that was sending the message would hang - forever.
- the thread that received the connection exception worked fine, but was not
my business logic thread
- this seemed very much like a thread deadlock issue. A coworker suggested
that it was a socket timeout issue, however I was not able to configure the
connection with the documentation I could find
- my issued has been resolved (for now) by using
transport.requesttimeout=10000
