Oh, you're quick on replying! Thanks.It would help to know what version of FreeNAS you are running, was this an upgrade from one previous FreeNAS version, is this a new Jail? Also, back up to step 16 or you can delete the jail and try again from the beginning paying close attention to steps 16 through 21a. Make sure you don't have any error messages there. All dependancies should be installed during the installation.
Also, if this is the New GUI (FreeNAS 11.2) then please try @hervon instructions and if you see something I got wrong, please point it out to me.
It's a fresh FreeNAS 11.1 installation and the jail installation is also fresh, I was following your excellent instruction.
I did erase my jail and did it all over again, no error messages at all in fact. I've noticed similar problems with other applications like OpenVPN and others where the same error appeared. There are a lot of suggestions to solve their problem, from reboot on an older previous version of FreeNAS to recompile the application itself. I did try the simplest solution I found and so far, I've not seen any errors. (But only after 10 hours of running MiniDLNA.) I do'nt have much experience of the library handling but following solution couldn't hurt trying: "ln -sf /lib/libc.so.7 /usr/lib/libdl.so.1"
