Dear Richard Huxton, Thanks for your quick reply.
only the first 3 values(HX, MASK, Rockey4ND) are file object's oid value. the other two are are not oid values. I have shown original output values displayed by postgresql client. I can explain more. 1. HX is a XML file. after downloading that file I opened that file in word pad application. In that I have noticed that nearly 20 characters of last line lost. 2. Rockey4ND is a dll file. I was unable to use that dll in my application. In both cases, I checked file size. Corrupted files are smaller when compare to the original one what I uploaded to postgresql. Usually this problem arises only after the database become large. Any suggestion to rectify this problem would be nice of you. Thanks. Regards, Purusothaman A On 5/23/07, Richard Huxton <[EMAIL PROTECTED]> wrote:

You've either got: 1. Some other part of your application(s) overwriting "value" 2. Old data still in "value" 3. On-disk corruption due to crashes/hardware malfunction. 4.

Hmm - well it's clearly not right, but I don't see how it can cause errors like this. > This problem occurs only few weeks after uploading files. You still haven't said precisely what the problem is. -- Richard Huxton Archonet Ltd
