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

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

Perhaps removing it will resolve this issue.

Matthieu Jacquart · Aug 24, 2017, 8:34 AM

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

Quazz · Aug 24, 2017, 2:35 AM

@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.

Matthieu Jacquart · Aug 24, 2017, 8:36 AM

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

Quazz · Aug 24, 2017, 8:42 AM

@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.

Matthieu Jacquart · Aug 24, 2017, 8:51 AM

@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 !

Matthieu Jacquart · Aug 24, 2017, 5:34 AM

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

Quazz · Aug 24, 2017, 11:38 AM

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

Matthieu Jacquart · Aug 24, 2017, 11:44 AM

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