Re: [PD] i lost my credibility
Hello, thanks for this suggestion. Yes, i could spend my time to optimized ubuntu to be more real-time. or i could use an optimized OS for real time stuf. i could install a dual boot or something like this. But i don't like this solution. mainly because it's an endless work that have to be done every time i change computer. and also because i use lot's of computer that are not mine. and because my computer is dedicated to lot's of different task, i don't want to reboot to use pd. so i prefer starting pd with a script that stopall unwanted stuff, and start them when i close pd. so, i made a script like this : gksudo stop atd gksudo stop cron pasuspender -- pd -noprefs -noautopatch -lib Gem -mididev 1,2,3 -listdev -r 48000 gksudo start atd gksudo start cron i don't know if is enough, did anyone already made something like this? thanks Cyrille Le 13/07/2011 17:33, Charles Goyard a écrit : Hi Cyrille, désolé pour toi, c'est super vexant ce genre de crash. cyrille henry wrote: did anyone ever experience a slow down due to ubuntu automatic script that should run on the background? how to easily disable them?

hello, thanks all for your answer. I'm now back home, and (thanks to Murphy's law), the problem can't be reproduced. I noticed a bad (physical) Fire wire connection on the cable after the performance, but now it is ok. maybe my audio buffer was too small and any other computer activity could break the connection between pd and jack (but not between audacity and jack) so the only valid hypothesis i can find is : - too small buffer for jack configuration - bad pd implementation of jack - automatic script in ubuntu that start in bad timing (friday 19h30) - bad priority between pd and ubuntu script it's just discouraging that thing worked for 60h straight and crash during the 20 min performance.

Re: [PD] i lost my credibility
Like I said I have been frustrated with jack and pd crashes, especially during a show, sorry that happened to you. I think though it is settling down again in 11, that whole pulseaudio stuff made things overly complicated for no reason. I have had issues with ffado alsa, sometimes jack fires right up, sometimes I have to run it from command line first. I can never tell, but once it's up and running I no touch.

[PD] i lost my credibility
hello, i need help to understand a major problem i had today. i'm unsing a old computer for a project, running ubuntu linux 10.04, with a presonus FP10 fire wire soundcard with jack. everything was running fine for weeks when we worked on this project. i boot this computer 3 days ago, start pd and everything was working wey well for all rehearsal. (i did not close pd since) the problem i've experience is that pd freeze during the performance. (fortunately, it was 10 000 Km away from where i'm living so i have no friend on the audience) This is my 1st unexpected pd freeze (when i'm not on edit mode) since i begin using pd, 11 years ago. i'm running pd vanilla with almost no externals thanks to Murphy's law, it occur in performance, and not in rehearsal. worst of all : i don't know what is the problem, and can't make things work again. So, the 1st thing i could imagine is a hardware problem, since the software was tested for month.

Re: [PD] i lost my credibility
I found that sometimes I had to start pd, then jack, then select jack. Which of course may not help you but it avoided the booting with jack first. I also found that sometimes jack was left running by something else and sometimes just selecting ALSA, then back to FIREWIRE seemed to clear things. I do not know why.

Re: [PD] i lost my credibility
Sometimes computers just crash - try using error-correcting RAM? I quote: It’s a well-documented fact that RAM in modern computers is susceptible to occasional random bit flips due to various sources of noise, most commonly high-energy cosmic rays. By some estimates, you can even expect error rates as high as one error per 4GB of RAM per day! Many servers these days have ECC RAM, which uses extra bits to store error-correcting codes that let them correct most bit errors, but ECC RAM is still fairly rare in desktops, and unheard-of in laptops. from http://blog.ksplice.com/2010/06/attack-of-the-cosmic-rays/ hello, i need help to understand a major problem i had today. i'm unsing a old computer for a project, running ubuntu linux 10.04, with a presonus FP10 fire wire soundcard with jack. everything was running fine for weeks when we worked on this project. i boot this computer 3 days ago, start pd and everything was working wey well for all rehearsal.

Re: [PD] i lost my credibility
Cyrille, I'll throw some long shots. I experienced pd(-ext) freezing on Lucid with the ffado driver, only during rehearsal. And also then jack refused to connect Pd. It was because of Jack zombification. Jack kicks out those clients who are too slow to respect the period indicated in jack's settings. Here, when this happens with the ffado driver (svn from several months ago) Jack won't start again unless I disconnect and connect again the firewire device. However, Pd should throw a message reading jack zombified calling shutdown handler. As you didn't mention such message, this should not be your case, but I mention it in any case. Are you with jack or qjackctl? Sorry if it sounds obvious, but can you connect manually Pd to your system playback from qjackctl? (if you have it installed) I had some other issues with ffado/jack/pd when doing hardware routing on my firewire soundcard with 6 outputs at once. But still don't know exactly why was it.
