<p class="MsoNormal"><span lang="EN-US" style="font-size:10.5pt;font-family:DengXian">My test env is without patch 22334, so priv->ssl_ctx is shared one. In socket_reset there is no need to free it. but if with patch 22334, it is absolutely needed to free priv->ssl_ctx
as well.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:10.5pt;font-family:DengXian">Following is the log captured from glusterfsd side while connection establishment, when accept returns, a new new_trans is allocated, and the socket_init input param is this
new_trans, because this new_trans has no option now, so in socket_init ssl_setup_connection_params is not called, so there should be no malloc done here, as showed from following log, ssl_setup_connection_params is called in socket_event_handler, and here
the ssl_ctx had been assigned to the shared one.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:10.5pt;font-family:DengXian">This issue is very easy to reproduce in my env, just “while true; do gluster v heal <vol-name> info;done” and check the memory of the corresponding glusterfsd , it is very
obvious increase.<o:p></o:p></span></p>
