I will appreciate greatly if you can diagnose the following crash
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.
