Hello,
how much shared memory did you configure for kamailio (the value of -m
parameter)? There are safety checks to ensure that there are available
256 to 512KB of shm/kamailio process in order to have safe ssl
operations. If you don't allocate enough and you have a high value for
children global parameter, then you can run easily into this constraint.
You can provide the output of:
kamctl ps
kamctl stats
if you want us to check if you allocated enough resources.
Cheers,
Daniel

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.
