What does a white cross on red background mean at the lower left of an icon in designer 8.51?

It looks a bit strange, the database is actually on a 6.53 server, so maybe it means xpages not available or something.pic:

Subject: icon

hi,

that means that there are errors in the database.

when you open the outline there has to be further icons like that one (at the positions where the errors occurs).
