It means you have corruption of some bitmap pages in your database.
These track how pages are used under Online.
Check out the Admin. Guide Version 5.0 Page 2-128 for more info.
0 means the page is not used, some how the bitmap for that page has
value 4 that says it is a "Home data page has room for another data
row".
I would either dbexport all databases, drop and recreate all chunks
and then dbimport all the databases or call Informix Tech. Support
for more help.
