It has been bad again today, because the assholes know no limits.
I added an additional 8GB swapfile.

is rumored to have said:
I decided to count how often the system on sa-vm has been getting so
busy it kills processes:
root@sa-vm:/var/log# zgrep -h 'Out of memory' syslog.{7..2}.gz
syslog.1 syslog |cut -c1-7 |uniq -c
4685 May 22
2562 May 23
9019 May 24
8925 May 25
4529 May 26
2699 May 27
348 May 29
2820 May 30
Most of the killed processes are 'rule.cgi' but according to dmesg,
there are also a bunch of cron, sh, httpd, and pigz processes running
at the same time, suggesting that this is a cascading problem
bottlenecking everything on the machine.
The drop 5/28-29 MAY be due to my addition of a few dozen /20 networks
with many sources of DDoS traffic to be blocked in iptables. I've
repeated that today. I have also restarted the "Loggy Jr." service
which appeared to have a memory leak (2.3GB RSS)
Unclear if there's any good strategy to make this less of a
whack-a-mole situation...
