There is a logfile checking utility a member here has created - it looks thoroughly for errors in the logfile, but I believe you have to have wdisplay in the root which you don’t but easy the create and make a logfiles folder under it, put utility in c:\wdisplay and run it with the suspicious logfiles copied into the duplicate folder. I’ll try and find the link.
Aha! I found it …

is the thread and the author HometownZone talks of it and the download link. May have to set some parameters up for NZ 9am times etc…
It does not fix anything but points out the errors in a file to print for followup manually. I will pm you my phone number as there is a bit of a procedure to get current logfile correct while still running live.
It primarily looks for duplicate lines and missing lines at end of and start of day.
