Flash sucking CPU cycles

Where does flash become a part of the RouterOS? And why is it sucking the life out of a RB750G Hotspot?
Users on the hotspot?

oooo, i wonder if thats IO Wait …

It’s not Adobe Flash… It’s flash storage. And yes, writing to it uses a lot of CPU.

How does it come you have so many flash NAND access?
I tried to reduce NAND write to a minimum level on my own 450G (though no hotspot).

He is probably using the transparent proxy feature of the Hotspot to get the web proxy involved. 750s have tiny amounts of storage so the cache is constantly being thrown out and replaced with new file objects.

Yes,
I’m using the transparent proxy. I understand it consumes memory, but what’s the alternative?
No trans proxy and and the router is crippled isn’t it?

Add: If you notice the errors from radius in log.

Radius accounting request not sent no response.
Does that error/log correlate with the excessive flash overhead?

FYI, I had a few unneeded firewall rules which i’ve deleted. And I was not using 127.0.0.1 in radius config or in hotspot server profile. Both were pointing to my public domain, and that config seemed to be ok. But, I can see now why that’s unnecessary.

Since cleaning up firewall rules and radius config, no recurrence of the flash issue. But, I’m waiting to see if the radius accounting request issue pops up again.
Thanks

Don’t proxy. A 750G makes a very, very poor proxy. You’re not getting much out of it anyway - the storage available is so small hardly anything is being served from storage, but it keeps being rewritten with new objects. Turn it off, and you should be fine.

Great, I’ll eliminate it.

hello,
i’ve got same problem on my rb133… but i’ve got everything disabled except minimum functionality…
what is going on ?

same problem, disable proxy

proxy is disabled, whoever i’ve got web-proxy in stores and i cant delete it..
shortly after reboot it is disabled and i can remove it but after few seconds entry is back and active

create a new store, set it as active, then remove the old (full) store.

ok 've deleted this unused store by creating new one that i also cant remove

why is this happening ?
this rb is working only as AP Bridge

do you use hotspot?

in first screen i’ve show enabled packages, Hot-Spot is disabled and unused on this device (also on GW if you ask)
routing, dhcp etc is disabled
i’m using only wireless and bridge

make a supout.rif file and send to support, we will check what is using the store.

ok, i’ll wait until cpu reaches 100% and make supout.rif
or it isnt necessary ?

yes, please wait until cpu is high, then make file

its gonna be a litle bit troublesome…
RB is rebooting when i’m trying make supout.rif when cpu is idle…

i’m suspecting power adapter (12V/1A), it can overheat and shutdown for a while… whatever

when i’ll have file i’ll send it to support

since i’ve created new and delete old store for proxy and cpu utilization back to normall
uptime 6d and everything is ok
