Same problem with 5.19b4 and nothing special in the logs.
Now I know how to reproduce the problem instantly, I just have to put
my computer in StanBy mode and Awake it.
Using Process Explorer from Sysinternals I see that stunnel produce a
permanent "Other I/O" flow when problem appear.
I/O Other : "The rate at which the process is issuing bytes to I/O
operations that do not involve data such as control operations. This
counter counts all I/O activity generated by the process to include
file, network and device I/Os."
OtherI/O is confirmed by Process Monitor that trace no File nor
Registry nor Network activity.
But as stunnel still respond correctly to a Quit menu or any other
menus and SSL requests I assumed that it may be some Thread going
crazy so I compared running thread between normal stunnel behavior
with the 25% CPU behavior and found that in fact there is a thread
that do no terminate correctly.
Here is the Thread's stack :
Hope it help...
