Blanck page and Apache error



  • Server
    • FOG Version: 1.5-RC8
    • OS: Debian 8.5
    Client
    • Service Version: 0.11.12
    • OS: Win10
    Description

    Since few weeks I often have blank page when using fog Web UI, with apache error. I had to wait few minutes so it’s return to normal. It’s seems to be related to “PHP Fatal error: Allowed memory size of xxx bytes exhausted” but previous parameter was 512M (which was a high value) and even update to 1024 (and reboot server) dont resolve issue !

    Thanks,
    Matthieu

  • @quazz Ah ok I understood.
    It’s ok for now, fingers crossed !


  • Moderator

    @matthieu-jacquart Only moderators can. So it hasn’t reoccurred? :)



  • Does someone know why I can’t mark my topic as resolved ?



  • @quazz I removed mod evasive with command “apt-get remove libapache2-mod-evasive” and reboot server.
    Put 512M for memory limit, I hope it will be fine, thanks for your help !


  • Moderator

    @matthieu-jacquart I’m not entirely sure for Debian.

    I think you can comment out the AddModule line in httpd.conf and restart the service.



  • @quazz ok, and how can it be removed please ?


  • Moderator

    @matthieu-jacquart It’s an Apache module which can be used for security purposes. FOG moved on though and handles its job differently now, basically.

    I remember having to remove it way back when it was causing issues for me.



  • @quazz ok, but what is “mod evasive” ?


  • Moderator

    Mod evasive hasn’t been used by FOG since somewhere in the dev release of 1.3

    Perhaps removing it will resolve this issue.
