CTG8414E The Gateway daemon could not write to the stream log file name
The log process was unable to open the log file.
This message is written to the error stream. The log messages are written to stdout or stderr, depending on whether the error or information log was being configured.
Check that the file system is not full, that the directory for the log file exists, and that the CICS® Transaction Gateway has the necessary permissions to write to the log file.
