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

[Daniel-Constantin Mierla]

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
