postgres database crashed

We have a following table xyz( id int , fname varchar(50), img image)<br />where image is a data type we have created
similarto lo.<br /><br />so when we executed an insert query on the following table :-<br /><br />insert into xyz
VALUES(2541, '/home/ravi/jdbc/2_down/76.jpg', '76.jpg');<br /><br />It works well for nearly 2500 images but from there
onwardswe obtained the following error and the database crashes.<br /><br />this is the bt we obtained on using gdb
