UMS is not stopping

[MetaRZA]

So waiting until the next day, UMS shutdown takes a lot longer.

It turns out that LoggerFactory.getILoggerFactory().stop(); also closes stderr. So I reorganized net.pms.PMS.shutdown() to close logging last. I now see that most of the shutdown delay is in MediaDatabase.shutdown(). I also added Runtime.getRuntime().halt(0); This means UMS now exits with code 0, instead of 130.

I don't know if this is helpful.

I also see things like

Perhaps my startup and shutdown script may be of some help.

[MetaRZA]

UMS is supposed to shutdown on SIGTERM or SIGINT without an issue. I hope to find out why it wasn't. I now suspect my DB was [edited].

What's more, your script is using SIGKILL, which is exactly what I was hoping to avoid.
