You you attach a screenshot of your DeployOptions property class properties (sort by Editable column, ascending order, and screenshot only the ones that are Editable)?
Also, are you specifying an deploy job instance name in the DEPLOY_OPTIONS_INSTANCE_FOR_REMEDIATION property of the Compliance job you're running?
If not, it could be that one of the default deploy options is not allowing the job to run if one target fails...
Im wondering if its a resource issue or something on the DB or AppServers... This just started happening this morning, last night it ran remediation successfully against 3000+ hosts (has been working without issue for the past month). The BLAdmin team is going to be applying security patches this weekend and rebooting the boxes. Hopefully the issue clears after that.
Always a good idea to get rid of potential gremlins before troubleshooting for real hehe. Hopefully that will get the issue fixed !
