Why do you want to optimize in the first place? What are you hoping to achieve? There should be an error message in your Solr log from the failed optimize, so see if you can find that. At least for some Solr versions, optimize can be quite memory hungry so a very quick guess is that you have hit an OutOfMemory. Not enough disk space is also a guess: Make sure you have 2*index size free space before optimizing as worst case for storage usage during optimize is a total of 3*index size. - Toke Eskildsen, Royal Danish Library
