Thanks again for the input, I have a much better idea of what I'm looking
for now. Currently I have a list of leaks that ends with a message
indicating that I have "10108 bytes leaked in 342 chunks." This number no
longer increases as more connections are received. However, am I correct
in assuming that the above number is the amount I am leaking per
connection, or is it the combined total leaked throughout the
execution of the program?
I have compiled openssl with more debugging information, and have included
the reference count information printed out below. Are the numbers
below a cause for concern, keeping in mind that the program currently
accepts an infinite number of connections, and thus (supposedly) frees
everything but the context information. My guess, which seems to have
been confirmed by list members, is that I'm failing to free an SSL_SESSION
object somewhere. I am calling SSL_free on my connection object. I'm not
sure what else to do.
