I just noticed this in my even log... Has someone had this? Anyone know what this means and how to resolve this?

It's benign - every morning we roll the log file over to a new file so no single file gets too big. At the same time we create an alias to the new file (which is named with the date of the log) called "indigo_log.txt" so that automated programs can parse the log file without having to specify a different name for each day. The error means that the server couldn't create the alias file, most likely because of a permission problem of some kind. The vast majority of people don't use the alias so unless you do you can just ignore it.
