WARNING EC1346: Unable to open file (1) for copy from local agent: [path]: [OS error message]
An error occurred while trying to open a large file created during the build from an agent running on the same host as emake itself for copying into emake’s own backing store. The specific file involved is given by the path in the error message. The OS error message provides the specific cause of the failure. Note that this error is typically not considered fatal because emake can rerun the associated job using a different agent.
Because the error involves an external system in this context (the filesystem on the emake host), the list of possible causes for this error is virtually limitless: a corrupted filesystem; hardware failure; insufficient permissions; and so on. Refer to the specific OS error message to determine the cause of the failure.
