None of the tinydns files have been changed when this bug started manifesting (nor the ELF or its data files). Any version of libc6 2.32-1/2/3/4 will cause tinydns to ignore queries after a while. dnscache runing on the same machine is not affected. tinydns doesn't crash and there is nothing unusual in its logfiles. If I kill the tinydns daemon then supervise will spawn another version and it starts working again for a while, then stops replying to queries. Rolling back libc6 to version 2.31-17 makes tinydns work normal again.
