Minimserver crash on Windows 8.1 (64bit)

[ppienter]

I installed minimserver on my Windows 8.1 64 bit pc, using the 64-bit version of Minimserver and found it to load very slow. Also a rescan is very slow (compared to my previous install on Windows 7 and even older server 2003).

The latest java and Minimserver with all updates is installed.

When doing a search for a track using my Denon app on iPad the minimserver crashes.

Here's the log output :

MinimServer[Mars] is running

Is there something I should check ?
