When Ubooquity scans the shared folders, it removes all files that don't exist anymore. If your network drive is offline, Ubooquity sees them as deleted and removes them.

So technically not a bug. ;)

But I get why this is annoying and other users already complained about it on this forum.

So I already have a task in my todo list to prevent Ubooquity form removing files from the database when the shared folder itself (not subfolder) is missing.

In the meantime, you could disable autoscan and perform scans manually when you are sure your network drive is available.

I got your file and I have the same problem, so I'll be able to investigate this week-end.

Technically your Java version is one year old, but this is completely unrelated to this problem. There is no reason (at least for Ubooquity) to upgrade your Windows JVM.

Could you send me the PDF file so that I can reproduce the problem on my side and investigate ?

Thanks for sharing your benchmarks.

I never took the time to seriously evaluate performance under heavy load as I have always seen Ubooquity as something you deploy on a device at home with a few users from your family.

But that does not means using it for a wider usage can't be done.

As for the performance of NanoHTTPD, they'll become irrelevant with the next version since I replaced it with Jetty.

There is still a lot of work to do before I can release it, but the Jetty migration itself is almost finished, so it will definitively be part of it.

I don't know the first thing about Freenas, but if anybody wants to build a Freenas plugin for Ubooquity (as long as it remains free), he/she's welcome.

I received your file and reproduced the bug.

It'll be fixed in the next version of Ubooquity.

But like I said, when the new version is out, you'll have to rescan all your files for "null" description to be removed.

Ok, I hadn't noticed your Java version:

Java version: 1.8.0_60

Your problem comes from a missing library in earlier versions of Java 8.

To solve it, you have to update Java to a more recent version (the latest version is 1.8.0_101 if I am not mistaken).

Well, there is no command, all is done in Java code inside the program...
