Re: 6.5 released!

Upgrade worked well on CCR1036.

However, I dont really use many features and I exported the config and placed at the root like config.auto.rsc. So even if the upgrade would brake my settings, it gets imported on startup, doesnt it?

Hi, I had this problem on 6.4. I did no update, but first I disabled all graphs and turned off saving to disk then waited for a reboot. After that I reenabled them and saving to disk and now all my graphs survived the last reboot. (However, I only use interface and resource graphs.) Bests, Semir

Re: Something fills memory CCR OS 6.2

Hi,
thanks!
Yes, I know. Also support told me it has it fixed. However, after the router restarted itself without any known reason, the leakage stopped.
So for now I'll wait a while until 6.4 has it's new buglist XD As I see it grows quickly... Also I need to minimize outages.

Re: Instability under ddos attack

As I saw 6.3 did have some update on gbit links, but Im still waiting for feedbacks on 6.3 issues/stability. Also I found that 500-700Mbit IPv6 DDOS traffic loads the cores to 100% (with 2 FW rules only), so ipv6 ddos above 700Mbit may have triggered the watchdog. But this does not answer the cases ...

Something fills memory CCR OS 6.2

Hi,
Im trying to resolve what fills the memory on my CCR with RouterOS 6.2.
Are there any tools for that?

Im not using any SW queues, address-lists are empty, logging goes to disk, graphs would go to disks if that was not buggy.

Please help.

Hi,
new exp:

the tools/profile shows 90% idle, while system/resources show 100% load.

even though the traffic was the same like minutes ago but then the load was 35%.

Any ideas?

Instability under ddos attack

Hi,

I experienced router restart under DDOS attack for the second time.

Also once when the network was under attack (1Gbit+), it switched it's ports off and on.

Is there a cause/solution for this?

Firewall rules execution speed question

Hi, I was just wondering if it maxes the overall execution of firewall rules quicker if I place logically connected rules in different chains? I mean that way the 4-5 rules connected together get executed only if the JUMP rule in the main chain is matched. But the jump could cause equally high load....
