Function COPY

Hi,
I use postgresql 7.0.3 in redhat 6.2.
I installed .rpm binary and work good.
But i find a problem during import text file
Using the function copy from a text file (about 250Mb of size) i can see
this error:

CopyReadAttribute: end of record marker corrupted

So, i can't import my data.

I try using small file, nothing to do..

I try with the "original" 6.5.3 in bundle with RH 6.2 and i get the same
result...

Any ideas?

Thanks.
