| Summary | 0003440: MidiBuffer reservation fails ("MRB: Unable to reserve space in buffer") using automation in a MIDI track | ||||
| Description | When using automation in a midi track, MidiRingBuffer::read tries to reserve 32718 bytes in a MidiBuffer, which only has a _capacity of 32716, which is the output of jack_midi_max_event_size (jack_port_get_buffer(midi_port, blocksize)), called on an empty MidiPort in audioengine.cc:245. It seems that this is the maximum size of a midibuffer jack assumes to be possibly required at the given blocksize. Ardour then stops resonding, printing "MRB: Unable to reserve space in buffer, event skipped" to the console very often. | ||||

To trigger the problem, you have to switch the automation state to "Play", and start the transport. |

Thanks. I can't reproduce it here. Could you run Ardour in GDB and get a backtrace by hitting Ctrl-Z at the console when Ardour hangs (and then typing thread apply all bt into gdb) |
