Importing Quotes

I am importing data into the Quotes module, it imports 100 records then crashes with the following message

Mon Oct 31 20:38:25 2016 [2168][1][FATAL] Caught error: Accessing static property ImportFieldSanitize::$createdBeans as non static

I have 8k records to import I cannot do this 100 records at a time.

Is this a bug?

check your timeout settings in php.ini, check this documentation regarding php.ini settings https://suitecrm.com/wiki/index.php/Installation, the section Upgrade prerequisites

best regards

Its not a timeout issue, I imported 5k+ products and it worked fine, I tried with just 500 quotes (file size 175k) and it did the same thing, import 100 then crash
