Cannot load number rows - Mailing list pgsql-general

Hi,

I try to insert  55000 rows into a table
The  firsts insert seems ok (few rows are OK )
then after a while I et the following erorrs
psql:c:/temp/usrweb/transactions.sql:55420: ERROR:  current transaction is
abort
ed, commands ignored until end of transaction block

What  may be the problem ?
Something I have to tune tio successfully  load my data ?

Thanks in advance
