| Summary | 0001785: adding many tracks at once causes a crash of either jack or ardour2 | ||||
| Description | Adding many tracks at once causes Ardour2 to crash, or to block jack and being killed by the watchdog, or sometimes to kill jackd, or even just to segfault. 'many' is 24 tracks on a slow machine (VIA Eden 1.2 GHz) and about 128 tracks on a faster machine (P4 at 3 GHz). Adding fewer tracks causes xruns in jack. It seems that the process of adding tracks blocks the processing-thread. It would be nice to avoid this. | ||||
| Additional Information | Steps to reproduce (although the results differ from time to time, and depend on many external factors like processor speed, period size, etc.): Create a new session Add many tracks in a single step Tested on ardour 2.0/Linux (slow computer, segfault) and on ardour 2.0.3 (faster computer, killed or jack died). Jack is 0.103.0, packages by Planet CCRMA/fc6. | ||||

Opening a session with the same amount of tracks (added in several steps) works perfectly well (not even xruns in Jack). |

I can reproduce this on a Mac G4 running Ardour 2.0.3. It does seem to be intermittent - it doesn't always crash the app. |
|
|
I suspect your jack crash is probably related to the -R option. Ardour fails to respond fast enough and jack aborts. |
|
|
I *can't* reproduce this. The GUI freezes for a few seconds but neither ardour nor jackd crashes. Although if I ask for 128 tracks I only get 125 due to limits of jackd (currently set to 128 ports max). I have a fairly powerful machine and I use jackdmp instead of jackd, and this is probably very relevant. |

this was believed fixed several months ago. other users have done tests with many tens or even hundreds of tracks. feel free to reopen if its still an issue. |
