Re: [reSIProcate-users] TLS memory leak of resiprocate 1.7????
The leaks appear to be under SSL_do_handshake and
ERR_clear_error. As far as I know - neither of the fn's return anything that needs to be free'd by the application. I suspect the leaks are in OpenSSL 0.9.7a itself - it is a very old release. Are you able to test with a newer OpenSSL version?

Hi,
I used sipp -t tl at 30 calls per second for about 48 hours, the total memory (SIZE) with top command did not change after several hours, but resident memory (RES) increased 2 MBytes for about every 4 hours. Each incoming call has a new TLS connection.
So I use valgrind to test for 1000 calls at one call per second with answer time 50 seconds, and wait for all call finished and all TLS connection destroyed, and then terminates valgrind. What I found is that some memories in TlsConnection are still reachable although all TLS connections are destroyed.
Is anyone aware of openssl shared lib memory leak ???
Here are some output of valgrind:
