Php out of memory errors on 2.1 development amd64 - bogonsv6 and pfblocker
-
I have increased that a few times already, right now i am at 100000000 (100 million) and i still get the same error.
Do you know if there is something i need to do after increasing this? reboot?

Yes, the same error pfBlocker gets but now in bogonsv6 list. Maybe a huge list too.
I'm not testing 2.1 yet but you can try to monitor memory usage while applying rules to see how much RAM it loads before error.

I looked at both of my php.ini files, ( i have a /usr/local/lib/php.ini and a /usr/local/etc/php.ini ) and there was no memory_limit key but there was a suhosin.memory_limit = 512435456
According to http://redmine.pfsense.org/issues/2214 suhosin was turned off temporarily in 2.1 so i'm not sure if the suhosin.memory_limit would apply.
In any event, a reboot fixed my problem, so apparently changing 'Firewall Maximum Table Entries' needs a reboot to take effect…
I created a phpinfo() script and loaded it into /usr/local/www and it shows 128M, but the 'suhosin.memory_limit = 512435456' equates to around 488M according to my calculator and http://www.php.net/manual/en/faq.using.php#faq.using.shorthandbytes so perhaps the default of 128M is in effect since /etc/rc.php_ini_setup doesn't set any 'memory_limit'.

None of the log messages you have posted have anything to do with PHP running out of memory. Those are only messages about the external commands that the PHP script executed.
-
ok, thanks, that make sense.
So can you verify that changing firewall maximum table entries needs a reboot? Everywhere i find that references this change doesn't mention rebooting, and changing that variable definitely wasn't working until i rebooted…
-
It's a chicken and egg problem.
You have to load the ruleset to increase the table size, and you have to increase the table size to load the ruleset.
Delete or deactivate some tables, fix the table size, save/apply, then add them back.

I'm seeing the same issue as chpalmer. It's just 2.1, nothing to do with pfblocker, as I haven't installed that.
Turning off ipv6 everywhere doesn't help, I actually had to turn off bogon filtering everywhere to make the error go away. (not my first choice, but probably not a big deal)
-
this is not as much a problem with 2.1 perse. It's pf that can't load the ruleset.
I think there is some contemplation how to go about this.
I've had no issues with pfctl running out of memory related to anything remotely IPv6 related.
-
I'm inclined to believe it's not actually memory issue, since I'm using 3% of the 4GB in this box. (amd64)
I think it's a bug of some sort, there was a similar issue back in October in this thread: http://forum.pfsense.org/index.php/topic,40953.msg211475.html#msg211475
EDIT: And /etc/bogonsv6 is actually empty.
-
that thread is entirely unrelated to this.
