DBimport error 212 106

We tried a dbimport and received the following errors. Any ideas how to correct ? $ finderr 212-212 Cannot add index. This statement attempts to add an index, either explicitly with CREATE INDEX or implicitly as part of processing a SELECT on multiple unindexed tables. In any case, some error prevents the index from being created. For more information, check the accompanying ISAM error code. Insufficient disk space is a common cause of this problem. $ finderr 106 -106 ISAM error: non-exclusive access. The ISAM processor has been asked to add or drop an index but it does not have exclusive access. For C-ISAM programs, the file must be opened with exclusive access before you perform this operation. Review the program logic, and make sure that it opens this file by passing the ISEXCLLOCK flag to isopen. For SQL products, the database server returns this error when an exclusive lock is required on a table. For example, this error appears when a second user tries to alter a table that the first user has locked.
