Rollback Issue due to screen rendering time out.

[satish]

Hi All,
         I have made a custom component under hot-deploy folder. This component is copy of the 'catalog component' and made some custom changes in this component. While  trying to upload the image, Image is upload on server success but image path not store on database. Sometime are also facing same screen rending time-out issues on web-tools and product page. Please help me out this problem.

Below are the server log:-
