Yes. And that’s true btw. KahaDB is still used for scheduled messages. But I have them disabled in the config. I *did* see some reference to scheduling in one of the stack trace analysis but I will have to go back and verify.
Enabling KahaDB as a module fixes the problem obviously. I’ll have to look at what made it on disk. I’m not sure what’s happening though because they are disabled in the config. Thanks.
