    Thanks for the report! You should have mentioned that you have a TTL of 1. I looked into this and there's some weird math going on. It sums the TTL and the current (high precision) time, then subtracts the time, then rounds the result downwards. Because time would have passed, this would always result in the value being rounded down to zero, and then it gets expired because the TTL was reached.

    Should be fixed in https://hg.prosody.im/0.9/rev/2c65f8be38aa
