Lots of issues around March patches breaking domain controllers due to an LSASS memory leak:

Given how similar Horizon brokers are to domain controllers, it occurs to me to ask... has anyone seen any problems since deploying the update? I'm tracking lsass.exe memory consumption on one of our brokers, and it looks okay at the moment, but it has me a little nervous.
