Re: [Quickfix-users] threading growth issue?

Alvin -

This sounds like it might be related to the between sessions socket
creation bug that was fixed in 10.0.0.

"Initiator will no longer initiate socket connections outside of the
session time.  Previously it would connect and immediately close
connection during every retry interval."

I don't know enough about the JNI implementation, but if the thread
spawned during the creation of the socket didn't get killed when the
socket was closed, it could cause the behavior you're describing.

You might want to try 1.10.2 and see if the problem remains.
