CrashPlan Fatal Java error after update to OS 6.6.1

I upgraded OS yesterday and now CrashPlan is crashing.

# A fatal error has been detected by the Java Runtime Environment:
#
#  SIGBUS (0x7) at pc=0x00007fa30bd09460, pid=26003, tid=140338276411136

# JRE version: Java(TM) SE Runtime Environment (8.0_72-b15) (build 1.8.0_72-b15)
# Java VM: Java HotSpot(TM) 64-Bit Server VM (25.72-b15 mixed mode linux-amd64 compressed oops)
# Problematic frame:

#
# Core dump written. Default location: /usr/local/crashplan/core or core.26003

If I manually start it from the CLI and then check status:

root@NAS:/usr/local/crashplan/bin# ./CrashPlanEngine start
Starting CrashPlan Engine ... Using standard startup
OK
root@NAS:/usr/local/crashplan/bin# ./CrashPlanEngine status
CrashPlan Engine (pid 30330) is running.
root@NAS:/usr/local/crashplan/bin# ./CrashPlanEngine status
./CrashPlanEngine: line 116: cannot create temp file for here-document: No space left on device
CrashPlan Engine is stopped.

root@NAS:/usr/local/crashplan/bin# df -h

Any ideas?
