Oh, send(2) on OpenBSD [1] says that the firewall may cause such an error. I guess no one ever hits* this since on Linux this is "very unlikely" to happen. I think the problem is my cron fiddles with the vm's firewall at the same time. I'll look into that possibility. Thanks for the hint! * according to my web search :p [1]: https://man.openbsd.org/send.2#EACCES Daniel
