Olivier,
Thanks for your email.
Presumably this is the same error as you saw before?
When you say you rebuilt sprout, please can you confirm you rebuilt everything
("make clean" first)?
Also, please can you confirm what you're using as your P-CSCF? If you're using
bono, is it possible that bono hasn't had this patch applied and it is that
which rejects the message?
(From code-reading in pjsip, I'm struggling to see how we'd hit this error if
the packet size really was 64k.)
Presumably your message is less than 64k long? (!)
Please let me know.
Thanks,
Matt

Subject: RE: Size limit of SIP messages?
Matt,
I have pulled the code from master, moved the limit from 4000 to 65536 on
Pjsip/sip_config.h and rebuilt sprout
However this does not solve the problem.
The registration is OK, and when the big message comes to sprout, I still have
the following log
02-06-2014 09:02:27.545 Error pjsip: sip_endpoint.c Error processing packet
from 192.168.0.250:39946: Rx buffer overflow (PJSIP_ERXOVERFLOW) [code 171062]:
I will go on looking for the problem but can't figure out where it fails...

Olivier,
Thanks for your email.
On which node was memcached giving errors? Sprout should only store
registration and authentication data (not PUBLISH bodies) in memcached. I'm
not so sure about ralf - are you deploying that/is that where you're seeing the
error? Can you give more information on this?
(In short, yes, I had expected the PJSIP limitation to be the only one.)
To get this function into master, are you OK to raise a github issue
(https://github.com/Metaswitch/sprout/issues) about this?
Both bono and sprout will need to be rebuilt (although they're actually the
same binary with different command-line parameters). For instructions on how
to build them, see
https://github.com/Metaswitch/sprout/blob/dev/docs/Development.md.
Please let us know how you get on.
Thanks,
Matt

Subject: RE : Size limit of SIP messages?
Matt,
Thanks for looking. I have also seen the pjsip limitation this afternoon.
I was wondering if we are sure that this is the only one (I also had errors on
memcached replica when too big messages where received)
I am using custom presence documents that may contain quite big data (small
embedded pics in JPEG format for instance)
For SIP over UDP, the max allowed message size is 64 KB. So it's quite
surprising that pjsip has a so small limitation internally. For instance, Jain
SIP has a upper limitation configured to 64 KB for UDP and uses 4 KB as minimum
buffer size for TCP
I can try to rebuild pjsip myself but it will make harder for me to stay up to
date with the latest release if I have to rebuild it at each upgrade
I guess that Bono is also using PJSIP. Is PJSIP installed as a shared library
for Bono and Sprout or have they both to be fully rebuilt to incorporate PJSIP
modification ?
Olivier

Objet : RE: Size limit of SIP messages?
Olivier,
I think this limit is controlled by the PJSIP_MAX_PKT_LEN constant in
sprout/modules/pjsip/pjlib/include/pj/config_site.h. If you increase that and
rebuild (you might need to do a "make clean" - I'm not sure how well PJSIP
manages its header dependencies), you should be able to resolve the problem.
Is that something you're comfortable doing?
Obviously, that would only fix it locally on your machine. I'm sure we could
increase the PJSIP_MAX_PKT_LEN constant permanently, but it would be useful to
know what the use case is - what data is being transferred in the PUBLISH
messages and why is it so large?
Please let us know.
Thanks,
Matt

Subject: [Clearwater] Size limit of SIP messages?
Hi,
In some tests I am doing there are some PUBLISH messages with a 8 kB content.
This messages are dropped by sprout with a "Rx buffer overflow" error from pjsip
Is there a way to increase this limit ?
Olivier
