first of all, happy new year!
I haven't yet upgraded a single production system to 8.8.5 (waiting for
the 8.8.6 fix for the virtual hostname issue for one thing) but have an
eye on the forums to judge by the issues reported if upgrading to 8.8 is
safe yet. Recently there were a few posts where people have problems
with ZCS stopping to respond either (or both) due to reverse proxy
issues or mailbox locking problems. Here are the threads:

Install 8.8.5 Web Stops Responding"

recv() failed (111: Connection refused)"

To Zimbra 8.8.5, Have Been Getting Numerous Lock Errors"
Has anybody else seen similar issues with 8.8.5?
I've seen similar locking issues already on 8.7.x, especially if macOS
Mail and Calendar were involved. But up till now they only brought down
a single mailbox, not a whole server.
