Hmm, as Nathan has already pointed out this is caused by pthread_create failing. I think you may be running out of resources and/or hitting a ulimit. This may also be related to the udev fd not being non-blocking issue Chris Dickens reported. I've just pushed 2 patches to master, one to log the error code when pthread_create fails, and a cleaned-up version of Chris' non-blocking patch. Can you please retry with the latest master, and tell us what the error code is (if it still fails) ?
