Jadetex overflow

[VKuznetsov@xxxxxxxxxxxx]

When I do a jade -d.....print.dsl -ttex at1.sgml, and then
jadetex at1.tex I get the following output:

This is TeX, Version 3.14159 (Web2C 7.2)
(at1.tex
JadeTeX 1998/10/12: 2.3
(/usr/share/texmf/tex/latex/psnfss/t1ptm.fd)
(/usr/share/texmf/tex/jadetex/isoents.tex
! TeX capacity exceeded, sorry [pool size=15573].

            Entupdownarrow{\ensuremath{\updownarrow}}% 2195
No pages of output.

This happens to any other input too (as you can notice from the error
message it
doesn't even reach input). Do I really have to enlarge & recompile tex or
can it
be fixed any other way?

P.S. Don't ask me why I don't do a sgml2latex at1.sgml.
It doesn't work for a misterious reason, says it cant generate 
system identifier for docbook. I tried all the stuff with paths and 
/etc/sgml*
