This issue paniced my home box about three times when I updated OpenJDK for my DLNA media server jail earlier this year before I managed to revert the jail to an older version. http://www.freebsd.org/security/advisories/FreeBSD-EN-14:02.mmap.asc With 10.0-RELEASE and Java, I was also affected by 14:07 which was causing application crashes and not system reboots. Not an issue for your particular case. http://www.freebsd.org/security/advisories/FreeBSD-EN-14:07.pmap.asc Jason
