You specified the log preprocessor option to have error and warning messages sent to errorfile rather than to standard output. However, the preprocessor cannot open errorfile because not enough disk space is available, or you do not have file-system permission to open the file. If insufficient disk space is available, delete files to make space available in the file system, or select another disk. If you do not have file-system permission to open errorfile, specify another directory or login with the required permission.
