<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Based on information-gathering in issue ASTERISK-19278, it appears that Asterisk is misusing OpenSSL in a way that causes a slow memory leak. From combing through main/tcptls.c, it appears that one foul-up Asterisk has is to never free any SSL_CTXs that are created. I have patched __ssl_setup() to properly free the SSL_CTX if either
1) We're about to allocate a new one.
2) Some failure occurs during setup.
While I have no confirmation that this is the same memory leak being observed in ASTERISK-19278, this fix seems necessary anyway. I'm placing this patch on Review Board because my unfamiliarity with OpenSSL leads me to seek confirmation that what I am doing makes sense and will not cause issues.</pre>

I will ask the reporter on ASTERISK-19278 to test to see if the memory leak appears to go away.</pre>
