Group of people tackling unending problem fail to meet expectations (4,5)

Ross

I believe the answer is:

come short

'fail to meet expectations' is the definition.
(as in to come up short for a task)

'group of people tackling unending problem' is the wordplay.
'group of people' becomes 'cohort' (I've seen this before).
'tackling' indicates putting letters inside (I've seen this in other clues).
'unending problem' becomes 'mes' (I can't explain this - if you can you should believe this answer much more).
'cohort' going around 'mes' is 'COME SHORT'.

I've seen this clue in The Hindu.
