text importer

[Stefoner]

Having to import more than 500000 records from text file 20MB,composed of 3 fields, and wanting to use text importer,
I find a block of the program, for other without signalling of error to the committed attainment of the quota 18100/18160 records.
The table has sufficente space in order to contain all the data sin from its creation.
what I must make??!??
You have suggestions?
Thanks for help me

Does this table have a primary key? If so, are there any duplicates in the data file?

If not, can you send me the data file and the table definition?
