Hey Guys,<br>
<br>
We are facing quite often this error: <br>
<br>
/usr/sbin/kamailio[16985]: ERROR:<br>
<core> [dset.c:435]: print_dset(): ERROR: redirection
buffeROR:<br>
redirection buffer length exceed<br>
<br>
When the error is generated, there will be a missing contact in
the redirects (not to mention that Kamailio will crash in
uac_redirect for versions before 4.2.0). <br>
<br>
Can anyone explain the nature of this buffer and whether is
affected by a single contact or all the contacts together building
the final redirect? How can we control what's in that buffer from
the script?<br>
<br>
This is our script part building the redirects, out of location
data:<br>
"""<br>
if(!reg_fetch_contacts("location", "$ru", "called")) {<br>
send_reply("404", "Not Found");<br>
exit;<br>
}<br>
if $(ulc(called=>count)) == 0 { # No contacts for this
user online<br>
sl_send_reply("404", "Not found");<br>
exit;<br>
}<br>
$var(i) = 0;<br>
while($var(i) < $(ulc(called=>count))) {<br>
$var(pathUri) =
$(ulc(called=>path)[$var(i)]{s.strip,1}{s.striptail,1}); #Strip
<> so we can apply real uri transformations<br>
$var(newRURI) = $(ulc(called=>addr)[$var(i)]) +
";ipbxep=" + $(var(pathUri){uri.host});<br>
if $var(i) == 0 {<br>
$ru = $var(newRURI);<br>
} else {<br>
append_branch($var(newRURI));<br>
}<br>
$var(i) = $var(i) + 1;<br>
}<br>
"""<br>
<br>
Thanks in advance for any kind of tip!<br>

looks like the overall buffer for contacts in redirect is 512 in
size, perhaps same value from early beginnings. MAX_REDIRECTION_LEN
in config.h needs to be changed to larger value -- should 1024 be
enough?<br>
<br>
Cheers,<br>
