Hi, shared memory not freed once TLS connection close means shm available memory decreasing for new connection that leads to the following error
*tls: ssl bug #1491 workaround: not enough memory for safe operation*
*TestCase:* 1. start kamailio 2. use sample program to establish tls connection and close imediately. 3. Kamailio Log is For first TLS connection tls [tls_server.c:189]: tls_complete_init(): tls: enough memory for safe operation: shm=63604096 threshold1=12058624 tls [tls_server.c:649]: tls_h_tcpconn_clean(): tls shm_available after shm_free: 63545192
For second TLS connection tls [tls_server.c:189]: tls_complete_init(): tls: enough memory for safe operation: shm=63545192 threshold1=12058624 tls [tls_server.c:649]: tls_h_tcpconn_clean(): tls shm_available after shm_free: 63489352
*Memory Leak:* for tls connection connection 63604096 - 63545192 = 58904 bytes not freed.
for tls connection connection 63545192 - 63489352 = 55840 bytes not freed.
I tested same scenario on kamailio - 4.2.4, 4.3.4 versions result is same.
Could you please provide the fix?
Thanks & Regards, Raja Chegondi.
