DOCBOOK-APPS: fop: outOfMemory using tables

Hi, is there apart from tables and list-items another way to have two 
different alignments in one line? What I want is a right-aligned figure in 
front of text (e.g. numbered headings). Using tables I soon (ca. at page 
150, i.e. maybe the 500th <fo:table>...</fo:table>) get out of memory.

Same problem everywhere?
TIA, David
