[upstream reported] Bug in byobu could bring up the 100 to load!

skbierm · 2012-07-27 09:07:40

I had occasional lockups with extreme hard disk activity in my Waldorf setup. At the end, after setting up some new conky-files yesterday, tomorrow morning I found the reason, it is byobu. Under circumstances, that I now could find out, you're systems load could grow far beyond 100 ... I got 161 today, had to photograph it via my mobiles cam ^.^

Well ... see for yourself (last screenshot ... and showing apt-cache byobu bug ...) http://666kb.com/i/c5v62rs2kjouz7uqe.png

The bug is easy reproduceable ... open a terminal, su as another user, start byobu ... and after a short while, you're load raises and raises, while byobu fire's up one apt-cache after the next (in the screenshot there are suddenly 30+ apt-cache's running in parallel).

Thanks to conky, I got for the first time a clue, what happened.

If I do the same with with tmux - instead of byobu - all is safe. On my wife's Ubuntu Precise and Quantal - this bug doesn't exist, so on newer versions (5.17 Precise, 5.21 Quantal) it doesn't happen.

I reported the bug upstream to Debian: Bug#682958: Acknowledgement (byobu spawns apt-cache without end ... and freezes that way the system by high load)

Nice work

Why does byobu spawn apt-cache at all?

Thank you, Corenominal! That bug really got me yesterday ... (thought before - it was Compton ... but nothing in the logs).

@SabreWolfy ... byobu normally shows automatically - how many updates are available on the machine you stumble upon, ... a handy feature for administrating (also all my machines are setup to automatically update themself) ...

And you do this on Waldorf? At least Testing is frozen now.

I don't get what is the point of your question, ivanovnegro, for me it looks like something got lost in translation. So, do I .. what?

ivanovnegro · 2012-07-28 11:25:16

I meant the automatic updates on your system, in this case rather upgrades. I find that risky on Testing/Unstable. But I do not know how you set up this on your machine.

I've sent patches to the tmux mailing list to address this problem by giving each job a persistent and per-process timeout, leaving the default status-interval as a catch-all.
