I've been testing a pre-release copy of v3.26 for mikrotik over the last couple of days.
1. It works, the system did not crash over the 4 days it was running (with hotspot etc) whereas previously (pre-3.26) any multi-cpu device would crash within 24 hours of a reboot while running the hotspot 2. There WAS a memory leak issue in the prerelease which mikrotik have now fixed in the newest release however I haven't had a proper chance to test this myself just yet so I would advise anyone testing this on a multi-cpu system to CHECK back a couple of times after you install it.
Other than that, thanks heaps to the mikrotik team for fixing the issue and I'm looking forward to seeing some incredibly beefy multi-core routers in the future
Update: Memory leak still seems to be present in the release version. Have submitted ticket and details.

I d/l'ed and installed 3.26 this morning on a Dell PowerEdge 2970 quad-core with 2GB memory.
Multi-CPU now seems to be quite stable (yay!), however, I still have a memory leak. Tried three different pair of matched memory and it is still there. Leak averaged 250 MB in a 3.5 hour period. I will wait to see if it stabilizes over the next 24 hours.
I am running the optional Dude package as well, since this is optimum to work with the different subnets on this router.
More if and when it develops.
UPDATE: 20090715 0950L After 5.5 hours, memory dropped to 651MB. First reboot since the installation of 3.26. Let's see if it was a glitch.
UPDATE: 20090715 2230L
After a little over 12 hours, we had leaked over a gig of memory. I have disabled the Dud(e) and rebooted the machine. Memory started out at 1757 MB and in 7 minutes is down to 1738 MB. Maybe it will stabilize. Let's see what the morning brings. Was the right version of the ROS posted on the website today? Seems to be still a memory leak problem even with Dude disabled.
UPDATE: 20090716 0520L
In almost 7 hours the memory leak caused about 150 MB of memory loss. This is much better than with Dude activated, but by no means acceptable. ROS 3.26 final still has a memory leak issue that really needs to get fixed.
Mikrotik, please fix up this memory leak, and things will be great with this ROS!
UPDATE: 20090716 1330L
Well, case closed. It will be fixed with the next release. Ticket No. 2009071666000112 elicited the following response from Janis:
"Hello, It is DNS related problem. We fixed it already, will be included in the next release. to avoid this you can disable DNS caching.
Regards, Janis Megis"
Well, that's not really what I was hoping to hear, and I hope this will be released fixed soon.

Did you write to support? with 2 supout.rifs - one with, other without memory leak (no reboots in between)
if you're talking to me, the 2 releases I've tried were: 1. 10/July - pre-3.26 release, multi-cpu working fine, memory leak over the weekend. 2. 13/July - pre-3.26 release, with some memory fixes, still has the issue.
I think the release I got then and the one that was on the mikrotik page a day later are different, so I'm going to re-downgrade / upgrade again to v3.26 and see how I go tonight.

Ok, upgraded again and the newest one still has the same issue. (made sure I had the right one, checked the hash etc to make sure it was what was listed on the MT download page)
But yeah, still has a memory leak, sent another supout.rif through.
We Have been Running 3.26 on or AMD athlon X2 box for about 32Hours. without a Full Crash. However the All of my hotspot users stopped working. All DNS requests stop working. the Solution was to disable and re-enable all the Hotspots on the Box.
So Hotspot on 3.26 is still not quite fixed yet. but it did not deadlock the box.

One thing I still notice is that when I reboot a box with multiple hotspots, sometimes not all the static dns entries appear. You'll need to disable and re-enable the relevant hotspots for them to appear again.
Just make sure you check this when/if you reboot etc.. I've reported the issue to MT as it's been around since v3.23 at least
All 3.x was stable on multi-core, only it was necessary to "/system hardware set multi-cpu=no"
Why would you Post that. That kind of attitude is why it took over a F@#$%$g year to find the Problem with hotspot, if you had been Following this thread you would know that setting "multi-cpu=no" did not fix the Crashing.
I am up to Five Days on 3.27, i have a not seen a problem.

It's still crashed on 3.27 after 1 day and 16 hours.
We've report to mikrotik and put new supout for them, but so far no reply.
WE're only use that machine for queue.
Got another problem ticket.. Hope they respond for this.
