I came across a little something yesterday related to DirSync.

If you use a value in the notes.ini variable DIRSYNC_DEFAULT_ARGS that is not in the list of allowed values ( load dirsync -? ), then DirSync does not start anymore.
More precisely, Dirsync starts, and quits immediately.

No big deal, but for an admin it is certainly helpful if DirSync prints a message on the Domino console indicating that an incorrect value is used in the variable.

There is a SPR #SPPPBYJLZZ for this, but it doesn’t really have a high priority. Rather a nice to have.
