Hello there, just to add a little note about this. In my case, ( I was using
the PlcConnectionManager, not the CachedConnectionManager), the number of
threads was increasing only between disconnections and reconnections, not
between requests.
If you look at my PR #2241 I used the channel Inactive event which is fired
when the device disconnects abruptly (unfortunately I could not test this on a
real physical device and so I had to rely on the modbus simulator). In the
handler, I propagate the event which closes the timer and shutdown the
tm(RequestTransactionManager). Both these objects are responsible of the
leakage, but the latter owns the plc4x-tm-threads, on shutdown it releases them.
At the moment I have an application running 24/7 which polls roughly 20
devices between S7(1200) and modbus and so far it is working fine.
Hope this helps.
