I had deployed the app last on friday and it got deployed successfully.But since, today morning the deployment is not happening at all.It is checking for conflicting process and failing.

I'm doing this from the webide and i'm not able to check what are the conflicting process and how to resolve it.
WebIDE lacks the ability to do proper investigation on deploying apps to SAP Cloud Foundry.
The best way to do this is to install the Cloud Foundry Multi-apps plugin (see this tutorial). This will allow you to use the local terminal to control the deployment (or alternatively use SAP Business Application Studio which already has the commands built in).
Then use the command
cf mta-opsto get the list of ongoing operations andcf dmol <operation_id>to download the logs for that operation.cf deploycan be used to abort/retry operations.
