OK - probably we should add in the wiki at pv_buffer_size a note to say
that for xlog messages, there is a dedicated modparam to set the
internal buffer size.
Cheers,

Hello,
you actually need to set the modparam for it:
-
https://www.kamailio.org/docs/modules/stable/modules/xlog.html#xlog.p.buf_s…
xlog module is using its own buffer, not the one from pv core file.
Cheers,

Hi, could it be caused by this?
https://github.com/kamailio/kamailio/blob/master/src/modules/xlog/xlog.c#L65
I tried to increment it, recompiled kamailio and the error
doesn't show up anymore
Thanks,
Enrico

Hello,
I pushed a patch to print more details about printed
size, current token size and overall output buffer size
in those error log messages -- the commit:
*
https://github.com/kamailio/kamailio/commit/44e48809a608d4de46d61198137cd66…
Can you try with this patch and send again here on
mailing list the error log messages?
Cheers,
Daniel

Subject: Re: [SR-Users] pv_buffer_size config value
actually ignored?

Hello Daniel, yes we do use that $avp for a log line
which is actually a big json, the $avp is composed by
multiple jansson_append calls and at the end an xlog()
calls prints it
Could it also be that I'm miscalculating because of the
encoding? 4K utf8 characters could be more than 4K (but
I don't think there are so many multibytes characters to
let it reach the 8K limit)

Hello,
where do you use that avp, because for the avp value
itself, that buffer is not used -- avp values are
stored in shared memory.
Do you use that avp in xlog() or other functions
parameters?
Cheers,
Daniel

Hi, I'm having some strange
issues with a somewhat
big $avp value, when it reaches a size of about 4K
I get this error:
29(47) ERROR: <core> [core/pvapi.c:1452]:
pv_printf(): no more space for spec value
29(47) ERROR: <core> [core/pvapi.c:1461]:
pv_printf(): buffer overflow – increase the buffer
size...
In the docs I read that the default pv_buffer_size
is 8K, I still tried to enforce it to something
bigger and checked the logs to be sure it was set:
0(384) DEBUG: <core> [core/pvapi.c:2062]:
pv_init_buffer(): PV print buffer initialized to
[40][16384]
But still when reaching the 4K size inside the $avp
that error comes out, is there any limit I'm not
aware of?
Thanks,
Enrico.
