Error in logs

[J7529]

Hello,

I have just checked my logs and noticed a lot of "swap_page_getswapspace():failed (See image below)

How would I go about fixing this?

Thanks,
Jord

What's the output from the swapinfo command and output from the grep command ?

[2.4.4-RELEASE][admin@pfsense]/root: swapinfo
Device 1K-blocks Used Avail Capacity
/dev/label/swap0 16777212 41544 16735668 0%
[2.4.4-RELEASE][admin@pfsense]/root:

[2.4.4-RELEASE][admin@pfsenset]/root: grep memory /var/run/dmesg.boot
real memory = 10737418240 (10240 MB)

grep memory /var/run/dmesg.boot

When I do swapinfo I receive the following output:
Device 1K-blocks Used Avail Capacity
/dev/gptid/2b57240d-1623-11e8-b 1048536 824156 224380 79%

Doing the second command doesn't give me any output.

What version of pfSense are you running ?

It looks like you are running out of swap space, the following should tell you the process that's eating all your swap space.

Run top -w, press o then type in swap

I am running 2.4.4-RELEASE-p2

Running that cmd the top results flicks between Squid, ntopng & clamd

grep memory /var/run/dmesg.boot should work.

How much RAM do you have ?

[J7529]

I have just tried running that command again but by tabbing out each word, I don't have a option for memory after typing grep

I currently have it set to use 4GB RAM

You probally need more RAM.

It looks like im using only 48% or am I looking at the wrong thing?

@J7529

The above screenshot is the current state, do you see errors in the log all the time ?

I have 8Gb of RAM and I never swap memory from RAM to disk.

Disable ntopng, does the swap usage change ?

[J7529]

I see error logs maybe twice a day they have happened since I posted this,

When disabling ntopng the swap usage doesn't move but I have noticed that the SWAP usage is 1023 assuming if I upped the RAM this would increase automatically.

[NogBadTheBad]

Upping the RAM causes memory staying in RAM and not being swapped out to swap ( RAM disk ).

Can you tie in the time stamps to what squid, ntopng or clamd might be doing ?

[J7529]

Just gone through the logs and can't see anything around the time where I received the swap errors
