Hi. Since the installation of PH 3.0 and FTL 2.6 I see my Memory usage "turned red" at 91.2%. 88.0% a few minutes ago.
Any issue or leave it alone?
BTW -- it's performing excellently! :<)

Can you post a screenshot of a terminal (possibly maximized) showing htop? If it comes from FTL we should investigate what is happening.
How many queries do you have in memory and how large is your memory (which device?).
Hi. TU. I'll work on the screenshot. Meanwhile I will need some help here ... "htop?" Kindly define that for me?
Trying to RDT in but the Pi v3 is responding really slowly More soon! :<)
More on htop can be found here: http://hisham.hm/htop/
It is a resource visualizer for both memory and CPU and will list detailed which process consumes how much of each.
In case it cannot be found, you'll have to install it using
sudo apt install htop
OK. TU. Looks like this issue is getting bigger. No longer do I have access via remote desktop and the web UI says "Lost Connection to API."
I'll go do a brute force reboot and try to get the needed info before resources are used up again. :<) I'll then proceed with "htop."

Hi. Here's a screenshot of htop in operation:
The Pi 3 is using a 32GB micro SD card. Presently I have a log file of 827.88kB (no idea what it was before brute-force reboot). Memory usage is running between about 16.3 and 17.9%. It's working fine -- for now. (This pi's sole mission is to run PiHole.)
Thanks for the tip on htop!
Rick
Thanks! Everything looks perfectly fine.
Maybe your issue was one of those that magically fixed itself unexpectedly. Nevertheless, we are of course here to help/discuss further in case you encounter any further issues with Pi-hole.
TU. That's certainly all i can ask. You've been exceedingly helpful!

Hi. More info. I returned to the office this evening and I see that memory usage is now 82.0% and climbing slowly. The "memory usage" icon is red. If I am reading this correctly, PiHole was using .2% of memory this morning vs 64.8% now. (The screen shot I sent you earlier today was made shortly after rebooting after I lost access to the pi via RDT and it "Lost Connection to API."
Size of micro SD card: 32GB
Computer: Raspberry pi 3
Query log size now: 1.35MB
DNS queries today: 5502
Should I downgrade to the previous version, I wonder?

Hmm, it is very strange to see your FTL consuming that much memory. You could attach the debugger if FTL is still running for you.
You may have to install the debugger first:
sudo apt install gdb
They follow the simplified instructions you can find here:
OK Will do. This morning I see the UI says "Lost connection to API, 740 and the graphs are not populating.
Can you get us a copy of the /var/log/pihole-FTL.log? Try cat /var/log/pihole-FTL.log | nc tricorder.pi-hole.net 9999 and you should get back a token.
Good morning, Dan. Presently, I'm running pihole-FTL under debug -- restarted as DL6ER suggested. Shall I assume if I open another window to do that that would be OK? One won't interfere with the other, will it?
It shouldn't, you'd just be reading the log file so no locking of anything should take place. Just want to check and see if there were any indicators prior to the engine falling over earlier.
OK. Tnx once again. Token is bcjb8rkj4f .
Thanks. I do see some of the init killing the process.

Interesting. The memory usage is climbing fairly rapidly. About 11% when it was booted, now 28%. (log file = 697.73kB.)
On the settings page, PiHole FTL indicates Memory utilization is 16.0% but used memory is 145.14MB.
The card is a 32GB card.
Does that seem right?
How does free look?
Mem: Total 945520 Used 494808 Free 450712 Shared 13004 Buffers 43388
That doesn't look too off the mark for now. If you could keep an eye on it and see how it behaves as time goes on though.
