Not able to insert the large data to HP-UX IA machines

Hi,

We are supposed to insert the large data which is around 200 k/row.
(Through libpq)

We are able to do it in HP-UX PA machines.not in HP-UX IA machines.
We can insert the data upto 46k in IA machines.(we have bytea field .and
most(all) of data go to this field)

When we try to insert the large data or data which is more than
47 k server will be waiting forever.(we are using pqexecparams to insert
the data)

Here is the sample output got using "tusc"
