Have you activated XDebug?

If you activated XDebug, you should deactivate it or set the maximum nesting level in the php.ini higher:

xdebug.max_nesting_level=500

  • I had one configurable product which had around 300 associated products. That might be the reason causing this error. Because of it the nesting level seems to be crossed 256 limit. – Mukesh Chapagain Sep 16 '16 at 5:30
  • Does this work for you @MukeshChapagain? – Kumar A. Sep 22 '16 at 11:38
  • Sorry. I think I had deleted some of the associated products before. May be due to less number of associated products, the reindexing worked before. However, now when I try adding a configurable product with 200+ associated products & also update xdebug.max_nesting_level to 500, I am still getting the same error. – Mukesh Chapagain Sep 23 '16 at 6:28
  • Did you try to deactivate XDebug? – David Nguyen Sep 30 '16 at 9:41
