Hello. Recently I started getting the following messages in the log, presumably leading to a system hang:

Code:: Jan 5 02:22:30 raspberrypi serviio.sh[162193]: [2426886.643s][warning][os,thread] Failed to start thread "Unknown thread" - pthread_create failed (EAGAIN) for attributes: stacksize: 2048k, guardsize: 0k, detached.

Is there anything I can do with it? Thank you.

You can increase the memory assigned to Java in the VMOptions file. I can't say where that file is located on your install, since you're not using Windows. Unfortunately, I can't recall the format of the command to add to the line. I thought I had it in my folder, but I just checked and it's not there.

Wait, I think I found it. Add -Xmx512m to the file I mentioned above. If 512m isn't enough, bump it to 1024m and try again. Make sure you restart the Serviio service after you make the change.

The JVM options are located at the end of the serviio.sh file in the bin directory of the Linux/RasPi install. You can set the -Xmx512M options there.

Good Luck
