Based on the logs it seems like device rejecting the Junos space request and responding back with the error due to premission issue in the file applications.xml
This issue arises when the `applications.xml` file becomes corrupted. To resolve this problem, follow these steps:
1. Remove the corrupted `applications.xml` file.
> start shell user root
% rm /var/db/idpd/nsm-download/applications.xml
2. Reinstall the IDP signature from the Security Director.
If the problem is persistent contact the Juniper TAC dSRX team.
