The default size limitation of console log (console.log) in Domino server is 10 MB. If the size exceeds 10MB, the contents of the log will be cycled and the old contents will be deleted.
However, with the amount of features available on Domino servers these days, 10MB would soon be reached. When something goes wrong with the Domino server, if we try to check the past status in console log, we may not be able to see errors and such because they have already been deleted. Changing the size limit after a problem by Console_Log_Max_Kbytes parameter has occurred is already too late to investigate.
So, we want to expand the default size of console log in Domino server. (ex. 1GB)
Since HDDs and SSDs have large enough capacity these days, there should be no problem even if the default size is large.
