    Hi

    we had trouble on ISPC 2 site - ran out of the space.

    CentOS 5.8 fully updated x86_64, ispconfig Version: 2.2.35

    Cleaned space, database had errors - repaired via ISPC management - now ok.

    Since than we are seeing problem - vhosts file is written with significant delay and no change is made to running virtual hosts until we restart httpd manualy.

    When I do manualy:

    strace /root/ispconfig/php/php -q /root/ispconfig/scripts/writeconf.php

    i get folowing error:

    OK problem resolved :)

    Issue happened after centos yum update (in which was bind chroot updated)


    DNS server in chroot was the cause for ispconfig config update not working.

    steps

    chmod 755 /var/named/
    chmod 775 /var/named/chroot/
    chmod 775 /var/named/chroot/var/
    chmod 775 /var/named/chroot/var/named/
    chmod 775 /var/named/chroot/var/run/
    chmod 777 /var/named/chroot/var/run/named/
    cd /var/named/chroot/var/named/
    ln -s ../../ chroot

    in ispc - management - server - dns

    zonefiles dir -> change the value from /etc/bind to var/named/chroot/var/named

    restart http + dns services in management or manualy

    done

    createch ISPConfig Developer ISPConfig Developer

    In our company, all the production servers (including those with ISPConfig installed) will get yum update disabled.

    Anyway thanks for sharing this.
