I've seen this issue resolved for some Linux versions, but I can't find a fix for the Mac server version. This is what I have:
Version 4.7 (build 3105) – September 11, 2012
Server jetty-6.1.x, java 1.6.0_43, Mac OS X (54.4 MB / 97.8 MB)
The problem is similar to what Linux users have posted - that the Subsonic server shuts down frequently. I don't know where I would find log files or configuration files for the Mac version. Right now, to keep the server running, I had to create a script that restarts the server twice a day to make sure it stays up. I am hoping that there is a better way than this.
Any guidance will be appreciated. Other than that issue, I really like Subsonic!
