Hello

We have several Mikrotiks working in production like a champ, but we have one CCR-1009 that has memory leaks. When we reboot it, it consumes almost 200mb, but each several minute it eats 1megabyte more until it only remains 90MB more or less (10% memory). Suddenly it recovers 500MB, as you can see in graphic.



it is over dimensioned, CPU it never reach more than 5%, if you see the mont graphic it's a line in 0%



It manages a three pppoe lines (300/300) with very little traffic, 20 hotspotclients, a SSTP server with 3 clients and very few traffic, 80 firewall rules, 54 mangle rules and 54 nat rules too.



Connections are always between 100-300: It's an officce route: no p2p, no games ... only dns, http








We are using the last stable packages









What can we do ?
Some advice?

Thanks

Exact, that was what has astonished me. We have several hapLite working uninterrupted for more than a year in a very heavy conditions for its hardware without any problem.
Maybe SSTP ? It's the first time we use a SSTP server, we normally used PPTP

I will do it this evening, because different offices use SSTP to connect to us. I will use PPTP during some days to see if SSTP is the problem and report it if it was the problem


As you can see, It has lost 7 mg in few hours



Thanks to all

Actually there are not really convincing reasons to use SSTP because both parts are MK routers. We use them because they are layer 3, easy to configure and pretty secure. Now I have downgraded connections from AES to RC4 to see if it helps.

I think I will follow your advice and we will move SSTP.

Thanks again

After 24 hours it seems more stable, but we must follow it

What have we done? Really we have done two things: Downgrade firmware to 3.27 because this is the firmware with stable packages, and two, downgrade SSTP from AES to RC4

Thanks

I will!

Thanks for your time and advice
