I've never tried this... I have tried against the hmm9 directory from Step 8 (monophone acoustic models), and hmm15 directory hmms from Step 10, and had no problems (though the hmm9 models were not that accurate...)

have you tried modifying the beam width parameters in Julius:
Beam width (number of HMM nodes) on the first pass. This value
defines search width on the 1st pass, and has great effect on
the total processing time. Smaller width will speed up the
decoding, but too small value will result in a substantial
increase of recognition errors due to search failure. Larger
value will make the search stable and will lead to failure-free
search, but processing time and memory usage will grow in pro-
portion to the width.
Default value is acoustic model dependent:
1000 (triphone,PTM, setup=v2.1)
Or why not just finish the acoustic model training and use tied-state triphones?
