Hello,

you actually need to set the modparam for it:

- https://www.kamailio.org/docs/modules/stable/modules/xlog.html#xlog.p.buf_size

xlog module is using its own buffer, not the one from pv core file.

Cheers,
Daniel

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/44e48809a608d4de46d61198137cd669c6a4763f

Can you try with this patch and send again here on mailing list the error log messages?

Cheers,
Daniel

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.
