Hi All,
I'm playing with instant messaging with a PJSIP client, but as soon as I send body with payload to about 100k I'm getting the error below:
Apr 28 09:16:52 ip-10-227-0-26 /usr/sbin/kamailio[2909]: ERROR: <core> [tcp_main.c:715]: _wbufq_add(): ERROR: wbufq_add(40552 bytes): write queue full or timeout (0, total 0, last write 51946505 s ago) Apr 28 09:16:52 ip-10-227-0-26 /usr/sbin/kamailio[2909]: ERROR: tm [../../forward.h:240]: msg_send(): msg_send: ERROR: tcp_send failed Apr 28 09:16:52 ip-10-227-0-26 /usr/sbin/kamailio[2910]: ERROR: <core> [tcp_main.c:3638]: handle_ser_child(): handle_ser_child: ERROR: received CON_ERROR for 0xb30ddcd8 (id 352), refcnt 2, flags 0x5092 Apr 28 09:16:52 ip-10-227-0-26 /usr/sbin/kamailio[2909]: ERROR: tm [t_fwd.c:1609]: t_send_branch(): ERROR: t_send_branch: sending request on branch 0 failed Apr 28 09:16:52 ip-10-227-0-26 /usr/sbin/kamailio[2909]: ERROR: sl [sl_funcs.c:387]: sl_reply_error(): ERROR: sl_reply_error used: Unfortunately error on sending to next hop occurred (477/SL)
And the app get

Kamailio is already set with tcp_rd_buf_size=204800
Does anyone can suggest how to fix this?
Thanks in advance, Roberto Fichera.
