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

[Enrico Bandiera]

Hello Daniel, here are the logs:

29(46) ERROR: <core> [core/pvapi.c:1457]: pv_printf(): no more space for
spec value - printed:7 token:5131 buffer:4096
29(46) ERROR: <core> [core/pvapi.c:1467]: pv_printf(): buffer overflow --
increase the buffer size...
29(46) ERROR: <core> [core/pvapi.c:1457]: pv_printf(): no more space for
spec value - printed:7 token:5129 buffer:4096
29(46) ERROR: <core> [core/pvapi.c:1467]: pv_printf(): buffer overflow --
increase the buffer size...

Thanks,
Enrico
