OK, I've debugged a bit into the lucid upstart scripts:
First, I can confirm the regression.
The oom_adj patch is still in place, which is the good news. The bad
news is, that the problem is now caused by the upstart script
/etc/init/ssh.conf
Apparently the author didn't understand how the oom_a
I think the debian patch had been applied in releases after Hardy. But
the daemon only resets the oom_adj value that it was originally called
with. So in Jaunty a DHCP restart script which had the oob_adj value of
-17 itself caused the same effect. See bug report #390556.

As work-around I would suggest setting SSHD_OOM_ADJUST to 0 in
