I'm a little stuck... Click here to teach me more about this clue!

'island in strife' is the definition.
'sumatra' can be an answer for 'island' (Sumatra is an example). I'm not certain of the 'in strife' bit.

'produces traumas' is the wordplay.
'produces' indicates an anagram (I've seen 'producing' mean this).
'traumas' is an anagram of 'SUMATRA'.

Can you help me to learn more?

(Other definitions for sumatra that I've seen before include "part of Indonesia" , "Some land" , "Large Indonesian island" , "A US mart on an Indonesian island?" , "Large island of Indonesia" .)

I've seen this clue in The Globe and Mail.
