It did not happen often, but when it happened, you will need to know how to fix it.The rescue configuration is a previously committed, valid configuration. You must have previously set the rescue configuration through the J-Web interface or the CLI.

During today's work, one of SRX firewalls got a problem to load regular configuration file, and it loaded rescue configuration. Here is what the console output told me:

For somehow, the regular configuration could not be loaded, and system used rescue configuration instead.
Fix is quite simple. Made a little change to configuration and commit it to generate a new configuration. Reboot and this time console showed the regular configuration loaded successfully:
