Public bug reported:
This has happened five times in the past week (four times in the past
36 hours):
kernel: compiz invoked oom-killer:
There is plenty of free core memory and almost no swap in use when it
happens. This is Xenial with kernel version is 4.4.0-141, which
contains fix to previously reported bug #1655842 "Out of Memory"
oom-killer bug. I only have one week of logs to go by, which contain
five occurrences. It has happened four times in the past 36 hours.
Sometimes it happens right after logging into the unity / lighdm
desktop (three out of five times), but not always. In four out of
five occurrences a postgres job was running and oom-killer killed
postgres. In the one other instance, postgres was quietly idle in the
background and oom-killer killed Thunderbird. Kernel messages in
syslog from five occurrences:
