iMSCP 1.2.1 - Serverlast sehr hoch (1.0 1.0 1.0)

    Hallo zusammen,
    ich bin ein Mann der älteren Generation, und mein Englisch ist einfach grauenvoll, daher bin ich dazu gezwungen es außschliesslich hier zu posten, man möge mir verzeihen. ;-)


    Problem:
    Nach frischer iMSCP Installation + 1 Domain hab ich dauerhaft eine Serverauslastung von 1.0 1.0 1.0 (ermittelt mit TOP siehe Screenshot) zu verzeichnen, obwohl der Server ja noch nichts zu tun hat, theoretisch. *grins*
    Die dauerhaft hohe Last wird durch einen Task "vlogger" erzeugt !


    Mein System:


    - Linux Debian Wheezy 7.8
    - vServer (Hosteurope/Köln)
    - iMSCP 1.2.1


    Server implementation in use:

    • dovecot
    • apache php fpm
    • mysql 5.5
    • bin9 (master)
    • activ SSL for the imscp Services
    • Backup future
    • IPv6 enabled
    • FPM Pool per user
    • chkrootkit
    • rkhunter
    • Pydio
    • Roundcube
    • Rainloop

    Benötigt Ihr Debug-Logs, erstelle ich diese selbstverständlich, und reiche diese gegenfalls nach.
    Dies ist eine erste Anfrage, falls die Problematik bekannt ist.


    Vielen Dank schon einmal jetzt für ein tolles Produkt. *respekt*

    Hello ;


    Please do the following:


    Shell-Script
    1. # aptitude install strace


    Once done, strace the process like this:


    Shell-Script
    1. # cd /root
    2. # strace -p $(pgrep vlogger) &>strace_vlogger


    Let run for one minute at least and then stop CTRL+C and provide me the content from the /root/strace_vlogger file.


    Note: Must be done when the problem occurs, else, information will be inaccurate ;)

    Thank you for your fast answer. I make what you need, but i think the result is wrong, there is a small mistake. :(


    I locate the actualy PID from the vlogger task (25344), and make


    Code
    1. strace -p 25344 &>strace_vlogger


    The file you will see is:

    Hello ;


    I'll try to reproduce the problem on Wheezy ;) As I see the problem comes from the ALRM signal ... I'll investigate and fix ;)

    Die Patch-Datei scheint nicht 100% zu funktionieren wollen, daher hab ich mich für eine frische Neu-Installation von 1.2.2 entschieden. Dort sieht es gut aus, denn die Hohe CPU-Last ist nicht mehr vorhanden! :thumbup:


    The Patch-Script make a little bit trouble. Now i install a new Version 1.2.2 on a new Debian 7.8 System.
    The Problem with the high CPU usage befor seem ok, great, thank a lot Nuxwin for fix it. :shy:

    Yes the 1.2.2 fixed that little problem with the vlogger, but don't forget to implement the other patch (see the announcement). 1.2.3 will released soon :)
