Problem

The Java VM working with Confluence (or any Java application) dies with a SIGBUS (0x7) error. This predominantly only happens in Linux. 

A variation of the following appears in the Java crash log:

# A fatal error has been detected by the Java Runtime Environment:
#
#  SIGBUS (0x7) at pc=0x0000XXXXXXXXX, pid=XXXXX, tid=XXXXXXXXXXXXXXXXXXXX
#
# JRE version: Java(TM) SE Runtime Environment (8.0_40-b26) (build 1.8.0_40-b26)
# Java VM: Java HotSpot(TM) 64-Bit Server VM (25.40-b25 mixed mode linux-amd64 compressed oops)
# Problematic frame:
# C  [libzip.so+0x117d2]  newEntry+0x62

Cause

The Java VM will crash with a SIGBUS error if there is insufficient disk space in /tmp.

Workaround

The workaround is to clear out and make sure there's enough space on the HDD (and allocated to /tmp). You will need to restart Confluence after the changes. 

Resolution

This is an Oracle Java bug traced at http://bugs.java.com/view_bug.do?bug_id=7007769  The bug seems to be corrected in Java 6u21, but the issue has been noted to happen sometimes in newer versions.
