[SR-Users] Problem receiving large payloads from JSONRPC-S

[Alex Balashov]

Hi,

I'm requesting 'dlg.list' from JSONRPC-S via XHTTP on a rather busy 
server, i.e.

event_route[xhttp:request] {
         xlog("L_INFO", 'action=ER-XHTTP-REQUEST | ret=LOG_HTTP_REQ | 
data={"method": "$rm", "path": "$hu", "source": "$si:$sp"}');

         # Digest challenge omitted.

         if($hu =~ "^/rpc") {
                 xlog("L_INFO", 'action=ER-XHTTP-REQUEST | 
ret=JSON_RPC_REQUEST | data={"path": "$hu"}');

                 jsonrpc_dispatch();
         } else {
                 xhttp_reply("404", "Not Found", "text/html", "");
         }
}

# curl --digest -v \
   -X POST -H 'Content-Type: application/json' \
   -H 'Call-ID: abc12' \
   -d '{"jsonrpc": "2.0", "method": "dlg.list", "id": "0deadb33f"}' \
   'http://sipus_adm:raSheinmet4@10.0.62.74:5060/csrp_rpc/'

and finding that when there's more than a hundred or so dialogs in play, 
Kamailio abruptly closes the connection in the middle of returning the 
output:

-----
				"tag":	"AF5DA9B4-6D5",
				"contact":	"sip:14045551212 at xxx.xxx.xxx.xxx:5060",
				"cseq":	"0",
				"route_set":	"",
				"socket":	"udp:xxx.xxx.xxx.xxx:5060"
			},
* transfer closed with 151674 bytes remaining to read
* Closing connection #0
curl: (18) transfer closed with 151674 bytes remaining to read
			"profiles":	["total",[root at proxy kamailio]#
------

I can't seem to figure out what parameters regulate this. I'm using the 
following TCP settings:

tcp_async=yes
tcp_connect_timeout=5
tcp_crlf_ping=no
tcp_keepalive=yes
tcp_keepidle=30
tcp_linger2=10
tcp_max_connections=4096
tcp_send_timeout=3
tcp_accept_no_cl=yes
tcp_wq_blk_size=65535
tcp_wq_max=20971520

But this doesn't seem to have had any effect.

Any help appreciated!

Thanks,
