Issue

From dmesg - 
Out of memory: Kill process 32788 (xxx-process) score 891 or sacrifice child
Killed process 32788, UID 400836, (xxx-process) total-vm:149579664kB, anon-rss:114693828kB, file-rss:240kB

Looking at the 32788 PID listing in dmesg, it looks like it is only using 37 GB RAM VSZ.
[ pid ]   uid  tgid total_vm      rss cpu oom_adj oom_score_adj name
