WorkerLog is reduced now thanks.
Re the logging, something further in the file is changing this.
If I run grep against the file for something simple like the character 1 it
outputs hits all the way down to:
2016-10-06 06:19:17 [Worker_1] Worker_1 wakes up
It then stops and outputs "binary file matches" as it sees characters in
the stream that aren't consistent with the file type.
Are "bad line-end sequence" and "unsupported_SMTP_line_terminator" things
produced by the higher WorkerLog setting and will they go away now it is
set back to standard or do I have to change something else to suppress them?
