One of our creative SageCRM admins created a custom entity in SageCRM 6.0 and was successfully using that entity for over a year.  Just recently one of his unrestricted users started getting the following error every time he tried to enter a new entity - eWare.eWareBlockContainer error '8000ffff' Unexpected Error  /crm/CustomPages/Entity/EntityNew.asp, line 120.   We looked into the SQL logs to discover that the new_Entity name field was limited to 32 characters and this user was continually trying to enter a 70 character first name.  The simple solution was to change the field length in SQL to 128 vChar.  This isn't the first time I have seen an odd looking error thrown when the data would be truncated and in fact we could use the edit option on the form and type in the entire entity name and the data would end up truncated.
