RB5009UG+S+in rebooting and out of memory and storage

Sun Jun 05, 2022 5:20 am

I had my my MikroTik RB5009UG+S+in for about 6 months and was flawless, but today all of the sudden it started rebooting every few minutes, 6 times so far in the a row. I think I traced it to out of memory issue.
I tried searching but I can't find how to check what's taking all the disk and RAM space. Any suggestions?

I think it may have something to do with the flash, as the sector write count seems off.
Only 138 writes in it's entire life seems impossible, and it also is the same as the write count since last reboot, that's impossible.\

Also the total disk size seems off, this should be 1024.0MiB but somehow it reports as 1025.0MiB on your device.

I think you should first do an update to the latest version ( 7.3rc2 ) to be sure it isn't some old bug.

Yeah you really need to update from that buggy factory version 7.0.4 / 7.0.5, I suggest latest testing 7.3rc1. using that on all my equipment without any problems right now

Thanks guys! I didn't realize there was an updated firmware cause I was checking it via "Auto Upgrade" option and list was empty. I finally got it updated to 7.2.3 (stable) firmware. Unfortunately disk and RAM are still near capacity. I feel a bit wary about using RC2 firmware, also it doesn't mention these specific bugs in the release notes... Anything else I can do to clean up disk space or reduce RAM usage?
Also I think yesterday's rebooted were related to huge concurrent files download I was running. It's done now and it hasn't rebooted since yesterday...
Was I under DDoS attack?

What do you mean, there is plenty capacity, are you reading the numbers correctly? It says FREE space
