<p>Hello,</p>
<p>as I said, watch the traffic on port 8000 with ngrep or some
other network sniffer to see what data comes there. You can also
start kamailio with debug=3 in config, more debug logs should be
printed to syslog to get the context of what is processed at that
time.</p>
<p>Cheers,<br>

<div>Thanks for your feedback.</div>
<div>I have a dedicated listen directive for JSONRPC</div>

<div>and then an event_route for it:</div>

if ($Rp != 8000) {<br>
xhttp_reply("403", "Forbidden", "text/html",

if ($hu =~ "^/RPC") {<br>
jsonrpc_dispatch();<br>

return;<br>
}<br>
</font></div>
<div><br>
</div>
<div>So, I'm already doing HTTP traffic only in port 8000.</div>
<div>The interesting part is that if I use kamcmd pl.list
pipe_INVITE, only the first log line is printed. Using curl,
I see the other 2 logs all the time.</div>

<p>Hello,</p>
<p>can you want the traffic on port 8000 and see if there
is no "unexpected" traffic there? There should be no
error message for parsing the first line of an HTTP

<p>The error message related the missing pipe can be made
debug.<br>

<div>Hi all,</div>

<div>I'm using pipelimit with the "clean_unused"
option to get rid of pipes that are not used for
quite some time. At the same time we are monitoring
pipelimit with a jsonrpc call similar to:</div>

<div><br>
</div>
<div>The above reply is valid because the pipe_INVITE
was not loaded yet, but the request makes kamailio
to log the following log messages:</div>
<div><br>
</div>
<div><font face="monospace">Jan 20 11:21:48 proxy1
kamailio[24474]: ERROR: pipelimit [pl_ht.c:519]:
rpc_pl_list(): no pipe: pipe_INVITE<br>
Jan 20 11:21:48 proxy1 kamailio[24474]: ERROR:

Jan 20 11:21:48 proxy1 kamailio[24474]: [466B blob
data]</font></div>
<div><br>
</div>
<div>Since the monitoring system does periodic
requests, those log lines get a bit annoying and
fill the log with ERROR messages that aren't really
errors.</div>
<div><br>
</div>
<div>IMHO the first log line should be converted to
DEBUG instead of ERROR, but I have some doubts about
the one from parse_fline.c:262. parse_first_line()
is used to process both SIP and HTTP. It makes sense
to log ERROR if SIP but not in the case of HTTP...</div>
<div>Regarding the "[466B blob data]" I really don't
know from where it's coming from.</div>
<div>I can submit a PR, but I would like to have first
some feedback from you.</div>

Thank you,
