Could be memory? How much memory are you running with? Are you seeing oomkiller messages in kernel logs? See #18 for more on the current memory limitations of this software

[trey-stafford]

Confirming that #18 is likely the culprit:

[156104.111631]  out_of_memory+0x106/0x2e0
[156104.111993] Out of memory: Killed process 59120 (python) total-vm:27372200kB, anon-rss:24053468kB, file-rss:0kB, shmem-rss:4kB, UID:0 pgtables:51476kB oom_score_adj:0

This is on a VM allocated with 24GB of memory.
