On newer systems, the upper hard limit for open file descriptors (see `ulimit -H -n`) was increased from 4096 to 524288. Due to how python-daemon closes potentially open file descriptors (basically stores them in a set, removes those excluded by config, and loops through all of them), the updown script was either killed immediately (by the OOM killer) or not ready yet when updown events occurred.
