Yes we are seeing delay, intermittent not loading of alarms and system summary on home page. Radius live logs also doesnt always load. Seeing high load average that gets corrected by an application restart but eventually start getting alarms for that...
Do you mean 2.7 patch 3? The TAC engineer seemed confident 2.7 was the way to go but I don't really want to go 2.7 without some solid evidence it is indeed stable.
We are seeing exactly the same issues after upgrading to Patch 8 on 2.6, from a TAC engineer I spoke with it appears that 2.6 is plagued with performance related issues and resource leaks.
