Hi,
I will appreciate greatly if you can diagnose the following crash problem:
I am using stunnel 4.05, working with webserver thttpd to provide a https solution, in linux environment. First I wrote down some noticeable behavior of stunnel.
1) stunnel each time spawns a thread to handle the https connection then destroy the thread. If I browse a lot of pages, then internally a lot of thread ( or process) got created and destroyed.
2) Sometimes after a https request is completed, the thread is still there. Only following request will trigger the thread got destroyed. Normally if there is no activity, just 2 threads left.
The problem: During some stress testing, such as multiple ( in my case, actually just 2 or 3) web browser simultaneously issues request to the web server in https, I found out in certain moment stunnel spawns more than 5 or 6 threads to handle the connections, sometimes it crashed without giving out any serious debug error messages. When it crashed, system resource of CPU and memory is still sufficient. Note than I already set timeoutclose=0, that should be done.
Best
Regards
