Component Interface Save Failed error

Dear All,

We are getting Component Interface Save Failed error for one of our functionality at the time of load.

Eg. when 1000 concurrent request come to system, system unable to process few(20) of the request and throws error as Save failed (0,0).

Below code is handling such cases:

try

{

.

.

.

If Not &oXiaYankdetailsCi.Save() Then;

                throw CreateException(0, 0, "Save failed");

            Else

.

.

.

End-If;

.

.

.

catch Exception &ex

.

.

&ex.ToString()

.

.

end-try;

When these 20 failed requested are processed again, system process these successfully and save the data.(So there is no data/validation issue)

Can anyone help on this ?
