Selvaganesan Govindarajan commented on TRAFODION-2780:
------------------------------------------------------
Rao suggested the following
Wearing developer hat:)... as far as I remember the code, what we can do is to
call breakdialog when the timer expires... which gets to the mainly thread
which will execute the disconnect that cleans up. As long as code is not
changed since I am out of touch:). It’s the same logic of cleanup when client
goes away and breakdialog is invoked. Might work?
Thanks
