hey guys...
so i have a css326-24g-2s+rm mikrotik switch installed at a site off an RB2011 but it keeps freezing up after about 4 hrs i disabled stp on the router but doesnt seem to have helped much..any thoughts thanks!!!

Had the same problem with mine. Freezing would occur between 5h and 11 days. Upgrading to SwOS 2.3+ solved my issues.

Grüße,
Philip

well will try that , although been to 2.x as well
