org.postgresql.PG_Stream.ReceiveChar(PG_Stream.java:143)

Hi,
I have been using SOFIA framework and postgres
database as a backend.
i noticed as the database started growing larger..
today
encountered some error while firing a query to save a
record. The table in which i am going to save the
record, has two columns having datatype text. the data
of these two column contains 2652 and 5817 characters.
If I reduce some characters from both columns, it
saves the record successfully. But i reduce some
characters from only single column(whether it has 2652
chars or 5817 chars whereas both have the same
datatype), it gives me the following error :--

The backend has broken the connection. Possibly the
action you have attempted has caused it to close.at
