Hi Mike,
 
Thanks for your thoughts !
 
I'm using 4.16 and I believe thats the latest version. Atleast I see its the latest one vailable on the download
page of the website. Or is there some other latest version I know not of ?

When I said *server*, I meant the Stunnel application. Sorry for the goofup. Even after these messages
the Stunnel continues to run and process new connections.

The latest update on the problem is - The m/c has not been shutdown for 6 days now. Now when I run Stunnel
it closes down in 15 mins. The "time-to-die" for Stunnel has steadily decreased over the past few days from
1 hour and now its 15 mins.
 
Still looking for the setting to UP the mximum number of concurrent threads on Windows :-(
 
Thanks n Regards,
Kunal
