mass update issue in banzai - " box:too many SOQL queries: 101"

You will probably need to file a support case with box.com to ask them to examine their trigger code on this object — if the trigger is throwing an error when editing 50 records via Skuid, then it will probably throw that same error when trying to mass update them via custom Apex code or Data Loader. Box’s package should get its own set of SOQL queries but apparently they’re not optimizing their trigger code to handle updates to large numbers of records concurrently.
