Long list, as of complaints (6)
I believe the answer is:
litany
'long list as of complaints' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for litany that I've seen before include "Long and tedious series" , "Long and tedious recital" , "Succession of requests" , "A long monotonous recital as of complaints" , "A series of prayers to God" .)
