Hi David,
Off the top of my head I notice that you do not call this as part of the
cleanup: SSL_CTX_free() [
http://www.openssl.org/docs/ssl/SSL_CTX_free.html# ]
There is also this: [ http://www.openssl.org/support/faq.html#PROG13 ]
Regards,
Jeremy

Hi,
I'm using tn3270 sessions running over SSL. I may have up to 124
sessions activated concurrently, although I plan to get up to 250
sessions at some point.
Whenever the sessions are stopped and restarted, I notice
intermittently that memory grows in multiples of 4K bytes.
I'm running on AIX 5.1, 5.2 and 5.3 and using openssl-0.9.8l.
There doesn't appear to be an obvious memory leak in either my
application or the OpenSSL stuff (all memory allocated when the
sessions are started are freed when the sessions are stopped).
Here's a summary of the code structure:
SSL_library_init();
meth = TLSv1_client_method();
RAND_seed();
ctx = SSL_CTX_new(meth);
while ([some telnet connection wants to do SSL])
{
ssl = SSL_new(ctx);
SSL_set_fd()
SSL_set_cipher_list();
SSL_set_connect_state();
SSL_connect();
do SSL_read(), SSL_write()
SSL_shutdown();
close FD;
SSL_free();
CRYPTO_cleanup_all_ex_data();
}
Any ideas would be appreciated.
Thanks,
David
