Hopefuly it works as expected. Older versions of shepherd are not relevant in this case. I’ve fixed it slightly differently in commit bf7e07d299b197891110fbd8c717badbab06a472, to avoid a file descriptor leak. Thanks! Out of curiosity: I suppose you’re explicitly disabling IPv6 by using a custom kernel or with an activation snippet that fiddles with /proc or /sys, right? Ludo’.
