Sleep Wake Failure macOS High Sierra 10.13.2

Since I updated to macOS High Sierra on December 18, I have been getting a Sleep Wake Failure on my 27" iMac. Can I fix this or do I need to take it in to Apple?

iMac, macOS High Sierra (10.13.2)

In fact I haven't seen the (sleep wake failure) error message and my iMac (5k, late 2017) hasn't rebooted since the last upgrade (10.13.5).


What I witnessed is that my connected disks (2 USB3 and 2 Thunderbolt) may get disconnected went the iMac goes to deep sleep AND (and this seems to provoke it) I have Adobe Lightroom or Photoshop open.


As for now I have mail, chrome and itunes open, my 4 disks are connected and show in finder and I've just woken it up from a few hours sleep and all went ok.
