Are you using BerkeleyDB 3.x?  There is a bug in ovdb.c, when used with
BerkeleyDB 3, that can cause these messages.  They are harmless.  At the
end of this message is a patch to ovdb.c that will fix this problem.
This fix should appear in an upcoming snapshot.

By 'cycbuff' I assume you mean CNFS.  A cycbuff is a fixed size, and all
of it is used to store articles.  There is no way to use space in a
cycbuff to store anything else.

With ovdb, the only way to make sure it doesn't fill the disk is to use
innwatch to monitor your pathoverview, so that it will throttle the server
to prevent additional overview records to be written.
