We've been running PRI's on 6608 blades for years. Last month, we upgraded from CCM 4.2 to UCM 7.1 Since then, we get regular 6608 port resets (like every night at 6PM) on several different blades at the same time.
All ports on all cards are defined (MPT, Gateway, Xcoder) and are registered to UCM. Sounds like something on UCM is triggering these events, but we are puzzled as to where to look.
BTW, blades all have latest firmware as supported by UCM7.1
