Boot looping after attempted virus scan

@dolf Probably the generated iPXE script output is screwed up. Please open http://your.fog.ip.addr/fog/service/ipxe/boot.php?mac=xx:xx:xx:xx:xx:xx (put in the MAC of your client) in your browser and post the full (!) output here - mask IPs if you like but please post the full script so we know what you see!

Output of that link is attached:
I did not expect to see HTML… Parsing the HTML renders this beauty of an error message:

@dolf Anything in the apache error log (ubuntu/debian: /var/log/apache2/error.log, redhat/centos: /var/log/httpd/error_log) when you request this URL in your browser? Just asking because the “An error occurred while invoking the map callback in…” is not very much information they give us.

Same info there:

array_map(). I don’t have time to debug the code, but I can take a guess that this is happening:throw new Exception(self::$DB->sqlerror());Don’t know why, though.

Any ideas for a quick fix, while you’re solving this problem? I wish I could contribute a solution, but I don’t have the time / energy to dive into the FOG code base at the moment.
-
Updated to trunk version 7645: No difference.
Changed LOCATION of PCs: Error message goes away and PC boot normally. -
@dolf said:

What exactly do you mean by that???
-
Oops, my post was very unclear due to the excitement of finally fixing this.
I use the location plugin. After updating the “location” field on all hosts (simultaneously using a group, not one by one), the error disappeared, and the PCs started booting normally.
-
@dolf Did you have the location plugin installed/activated before? I am pretty sure this error shouldn’t happen on a clean fresh install - do you think?
-
Yes, I installed the location plugin a few months ago. In March, I think. I never used the virusscan feature before installing the location plugin. Don’t have the resources to try that now, either.
-
Ok thanks for letting us know. So I guess we are save to solve this now.
