JRE regularly crashes -- unhandled signal 11

[jazzhole]

Hello ~~

I've installed Subsonic server version 5.2.1 on a Banana Pro (http://www.lemaker.org/) running Ubuntu (http://www.lemaker.org/resources/9-257/lubuntu_for_bananapro.html). The Banana Pro has a SATA port. I've connected it to a 1TB HDD and am happily streaming music to my Sonos speakers, my Mom's Sonos speakers, my phone, browser, etc, and generally having a great time.

However, I'm experiencing a behavior that I've been unable to find any mention of on the web with regards to Subsonic or Banana Pro. Every few hours, Java will crash. Here is the error message in /var/subsonic/subsonic_sh.log.

#
# A fatal error has been detected by the Java Runtime Environment:

I don't know whether this is normal, but subsonic_sh.log also has thousands of lines of this. Every few seconds a new value gets written.

The "46556K" stays the same, but the first two values slowly creep up over time. I do not know what they mean.

When I restart subsonic it works fine, then after a couple hours the same thing happens. There doesn't seem to be any specific action that causes it. It's happened repeatedly both when the server was streaming music and when it was not. It's never happened on the same song either, or if it has, that seems to have been by chance.

I'm also going to post this on the Lemaker Boards and will update this post with a link to that post. My post in Lemaker will link here as well.

Thank you!

When I ran SS on a debian Dockstar (years ago now), openjdk did this...the Oracle/Sun version fixed it. Give it a go...cheers!
