Also tried:
modparam("tls", "low_memory_threshold1", 0)
modparam("tls", "low_memory_threshold2", 0)
same error.

And by default, compression is disabled. So strange error.

Hi All,

Need some help of setup TLS on Kamailio.
Currently my Kamailio TLS works, but only support one client register successfully. If there's another client want to setup TLS connection, it shows:
tls [tls_server.c:392]: SSL error:error:07064041:memory bufferoutines:BUF_MEM_grow:malloc failure.

I have modified /etc/default/Kamailio
MEMORY=256
But the error is still there.

The client A and B share same private key and Trusted Certificate. I don't know if this is correct or this is the cause that second TLS failure.

Can anyone help me? I can provide log or config if necessary.

Thanks,
Derrick
