thanks for attention
Does this problem exist in ROS 5.x?
I never saw this on RoS v4 or v5. The problem in those version is that you use a high amount of your CPU for the firewall rules - every single PPPoE Session creates a 2 new entries into your firewall to change TCP MSS. In version 6 all sessions got just 1 rule (it can be the problem in version 6, but I can't stick to this explanation).
BTW my platform is RB1100AHx2 and ppp connections has not reached 600 yet.it is now about 450
Hope mikrotik do something soon...
I see it's not only the number of connections that matter. It's also related to CPU usage. For example a in a server with 200 sessions and 20 of them consuming 10 Mbps of bandwidth I think the problem would be exactly the same... But I am not producing this kind of scenario so, I can't say this is true. For now I am going into a measure of how many sessions I got before the problem appears.
I've been sending message to the forum since the begining of the problem but no lucky. The best version until now it 6.0rc14.
