iProcurement : Error as "Internal server error"

Hi Team,

we are trying to process a requisition with 41 Items and 50 distribution in each item. when we click on Apply after entering the project information, system is giving as Error e.g Internal Server Error on every 5 min processing.

What i mean to say in short that the application is throwing error if lines are more in the requisition  and for lesser lines the requisition is working fine.

We did checked and found that the profile options values do match for the two profiles as below

"ICX: Session Timeout" = 30  and

s_oc4j_sesstimeout = 30

Please help .

Regards,

Yogesh  Sondkar
