Check the Orchestrator server and try to find out if there is enough free space available on the C drive. Perform some cleanup in order to free some space. After the cleanup, try to publish again.
Possible next steps to mitigate and also avoid this issue:
- clean up more space on the C drive
- increase the C drive disk
- move the Orchestrator storage for packages and libraries to another disk
- monitor the Orchestrator and SQL server resource usage in order to avoid issues like this.
For the Orchestrator storage location, please see below documentation link.
