pfTop hangs my GUI in 2.5.2 RC
-
When starting pftop by ssh it directly hangs without any output.
running pftops:
ps -ax | grep pftop

Curious. That isn't happening at all here.
If I run the command at the CLI it dumps data and immediately exits.
Are you certain your entire system (kernel and base OS) are running the correct and matching versions of 2.5.2-RC?

Maybe connected:
It hangs my FW, when there are 4 proccesses like this...

Indeed pfctl and pftop are not very happy, when looking at cpu usage...

Can you share your

Any large pf tables/aliases? If so, how large?

Couple of our networks, like 12x 192.168.0.0/24 networks, couple of dns aliases,
did have bogus network on in the interface config, and disabled it now, but i think you have to reboot... -

I thought maybe https://redmine.pfsense.org/issues/10414 had popped back up, but I can't replicate it using the commands that used to trigger it before. It's worth trying on your hardware though to see what happens.
Do you have bogons enabled?
If so, try the following commands:
$ /etc/rc.update_bogons.sh 0 $ time pfctl -t bogonsv6 -T flush $ time pfctl -t bogonsv6 -T add -f /etc/bogonsv6 $ time pfctl -t bogonsv6 -T add -f /etc/bogonsv6(yes, that last one is done twice)
You may have to reboot before doing that if it's already in the bad state it was in before.

I had similar result.

Before the upgrade not a single issue wigh beta...

OK, so at least we know it isn't the same bug coming back to haunt us, though that would have likely made tracking down the cause and resolution much easier.
From your earlier output, the
pfctlcommands getting hung up are dumping the state table contents.Try each of the following, but no need to post the individual state output, just the timing:
$ pfctl -si | grep -A4 State $ time pfctl -ss $ time pfctl -vvss -
State Table Total Rate
current entries 1434
searches 3714325 359.4/s

removals 136676 13.2/s4.50 real 0.01 user 4.48 sys
1.32 real 0.01 user 1.30 sys
-
Okay, after a reboot the pftop page works again.
CPU usage was back to none. Then a pfctl -ss was running long....
After it ended I run:
pfctl -si | grep -A4 State State Table Total Rate current entries 2407 searches 404293 546.3/s inserts 20698 28.0/s removals 18291 24.7/s time pfctl -ss 0.141u 140.191s 2:20.52 99.8% 203+177k 0+0io 0pf+0w time pfctl -vvss 0.157u 87.638s 1:28.08 99.6% 203+177k 0+0io 0pf+0wAnd perhaps these aliases add a lot of ipv4 and ipv6:

Hmm, it definitely shouldn't be taking that long to print out only 2400 states.
-
Block bogon networks was now on before reboot and is still...
pfctl shows up in top every now and then and uses a lot of cpu...
-
It's not likely related to bogons or aliases/tables at this point, but something in the state table.
I've started https://redmine.pfsense.org/issues/12045 for this, and one of the other devs has a lead on a possible solution.
We're still trying to find a way to replicate it locally yet, but no luck.
