You may also more memory than you have in you system, as lha sets up some kind of file name cache which is done before starting the compression.

I moved to tar gz to avoid such issues. For backup purpose I simply compress the drawers directory wise. Each game and each app gets one separate archive. Same for c,l,libs, devs,locale, morphos, ... This avoids an archive split and an easy way to install/restore only the stuff needed. You also do not loose all data,if the archive gets corrupted or lost.
