Hi, I tried to run Moses to produce N-best lists with distinct hypotheses (setting -nbest-list <file> 500 distinct). Although I also set "-use-persistent-cache false", the memory usage continues to grow from sentence to sentence during translation. The memory consumption drops only 2-3 times in the first 100 sentences as opposed to after every sentence. After 100 to 150 sentences, the program dies with bad_alloc.
Do you know what causes this problem? I run this on a task with about 700K sentence pairs (GALE-type data), setting stack size to 100, stack diversity to 10 and max-trans-opt-per-coverage to 15, and had no problems running translation with single-best output only. Thanks much, Evgeny.
