Grok Parse Failure (Diagnostics.log)

I'm seeing a few of these `_grokparsefailure` coming via supposed `ci_log4net`:

`file:///*/Logs/InstructionProcessorGateway/Diagnostics.log`

    481516234,LEVEL1,New/Accepted/ITP,18:50:13.587,62.4016,100,2
    481516235,LEVEL1,New/Accepted/ITP,19:16:46.768,46.7979,100,2

Fix the analysis.
