Ok thanks.  I also forgot to mention these are websocket SIP calls to the Kamailio.

I also ran into a thread after googling is to update the following in tls_server.c

#define TLS_RD_MBUF_SZ 65536
#define TLS_WR_MBUF_SZ 65536

I will try both options.

Thanks again!

Hello,

this seems to be related to the SIP message max size, not to the tcp buffer size.

You have to recompile kamailio after changing BUF_SIZE in the src/core/config.h.

Cheers,
Daniel

Hey group,

I was wondering if there is a way to control the websocket buffer size to support large SIP messages.  I received the following error when sending content-length of 65000

2021-01-26T17:32:19.251408+00:00 sjomainkama50 kamailio[31871]: 109(32008) WARNING: websocket [ws_frame.c:482]: decode_and_validate_ws_frame(): message is too long for our buffer size (65535 / 66151)


I am assuming this is controlled  by the tcp_rd_buf params which I have set to 131k:


tcp_rd_buf_size=131072


and this is my tcp_wr_buf params:

tcp_wq_blk_size=131072

tcp_conn_wq_max=131072



Please advise.


Thanks.
