I had an error with minimserver and it stopped. Tried it but error logs (minimserver-out.log) said:

Invalid maximum heap size: -Xmx250mx
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

Removed the file 'minimstart.conf' and it worked. Rebooted NAS. Added the file again and the same error. The only way I could fix was by removing the file again.

The issue surfaced after trying to write genre tag data to some mp3/flac files. The tag value had previously been 'XXXX' and then it was blank and then it was 'XXXX' again.

I could not get a rescan to recognise the tag value after it had been set back to a value it previously had (prior to being blank).
