Yes exec_id for files can seem strange, but here we are speaking about virtual files that are related to the image of the process being run, these files are in reality just some portion of the process memory.

The oom killer will kill other processes including getty,klogd,... even root owned ssh. -- tixxdz http://opendz.org -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
