Quick Start Guide for Installing JRiver Mediacenter 23 ARM on a Raspberry Pi
mp48:
I need some help with Media Center 23. It is running on a raspberry pi 2 and installed according to this thread. The MC is running in headless mode. The MC is running well for about 2 to 3 days and then MC is stopping/crashing, although the raspberry pi is still running (I can ping it and also connect via ssh). When I try to connect to the MC via JRemote or Gizmo, I get a message "Java refused to connect". After rebooting MC is running well again for another 2 to 3 days. I already installed a crontab for the user pi and the root for a reboot every day at 1 and 3 am every day, but still MC stops.
The frequently manual rebooting is not the right solution for me, especially because the users of the MC are not pc experts. Has somebody a good idea how to solve the problem?

It's possible the power supply isn't adequate for the attached devices, if any. Please describe your configuration.

Thank you for responding. I am pretty sure, that the power supply is not the problem. The power supply is a raspi 5.1V, 2.5 Ampere power supply. The raspi is running on LAN and the only connection is one external USB harddrive 2.5 ", 500GB for the music data. The raspi is running 24/7 days and in the beginning I found a problem with the router which had only a lease of 1 day. I changed that to a fixed ip address and then the raspi run for about 2 days. I am not sure if there are running some logs under MC23 ? Nevertheless I implemented a crontab for restart every day at 3 am. I am controlling the MC via JRemote with the iPad or EOS with the android tablet. The music is playing in three different zones, but only one zone at the time.
I am not quite sure, but the last time the MC23 run for 3 days (which was record !) and my daughter started her old android tablet with gizmo to control the music. After that the MC crashed again. Can it be that the old gizmo is not any longer compatible with MC23 on raspberry pi?

Did you pre-build all thumbnails and set the thumbnailing priority to low? If using gizmo triggers a crash it's almost certainly an issue with running out of memory while building thumbnails (triggered by browsing in gizmo). Did you use any of the auto-restart options in the top of the thread (i.e .the systemd services)?

The drive may draw more power than the Pi can supply. Please read this:
