Error while reindexing Catalog Search (Fatal error: Maximum function nesting level of '256' reached, aborting!)

[chapagain]

Preconditions

1. I am using Magento version 2.1.1
2. PHP version 5.6
3. I have sample data installed in my Magento site.

Steps to reproduce

1. Add a configurable product with around 300 associated products to it.

• Login to admin
• Go to PRODUCTS -> Catalog
• Add Configurable Product (Click on Add Product button & Select Configurable Product)
• Under 'Configurations' section, Click on "Create Configurations" button
• A popup window appears which has 4 steps to complete.
• The first step is "Select Attributes". Select 'Color' & 'Size' attributes.
• Click 'Next' button.
• The second step is 'Attribute values'
• I have 12 Color options and 20 size options (Note that I have sample data installed in my Magento)
• I selected all color options and all size options
• Click Next button
• The third step is 'Bulk Images and Price'. Don't change anything here. Just click 'Next' button.
• The final step is 'Summary'. It shows the list of associated products. Click 'Next' button.
• The popup windows is now closed.
• Click on the 'Save' button to save the product.
• It will take a while but the product will be saved finally.

2. Then, try to reindex Catalog Search with the following command

php bin/magento indexer:reindex catalogsearch_fulltext

Expected result

Expected to get message like "Catalog Search reindex has been completed successfully".

Actual result

Got the following error:

Solution tried

My xdebug.max_nesting_level was set as 256. I updated php.ini and set it to 500.

xdebug.max_nesting_level=500

But, that didn't solve this issue.

@chapagain thank you for your report.
Could you please describe with more details how you execute the first step: 'Add a configurable product with around 300 associated products to it.'?

[chapagain]

@veloraven I have updated the question. Could you please check?

[sevos1984]

The same issue here #6282. Closing as duplicate.

@chapagain I have temporarily disabled xdebug from php.ini and this issue got resolved.

@siju-corra I am facing the same issue, have you fixed the issue permanantly?
