[RB433AH] Bad blocks, spi profile

Hi there,

I’m using an RB433AH as a AP with PPPoE server. I’ve noticed increase of CPU using and bad blocks.
I also noticed a new profile item. Look at the screenshot. I looked at the wiki (http://wiki.mikrotik.com/wiki/Manual:Tools/Profiler) but I could not find anything about “spi”. What process is this? Is there any connection between CPU, bad blocks and SPI?

It could be. Do you log to flash? - Old scool tip - dont. It will break Your flash.

Run a check-disk to the router.

Thanks for your answer.
I’m not logging on flash. Look at the screenshot.
How can I do a check-disk via RouterOS?
What is spi on profiler?

spi means something is actively using the disk (“spi nand”)

What could be the cause in my case?
What do I have to do?

make supout.rif file and send to support, mikrotik will check which process causes this

Thanks, I sent it!
