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.
