We've recently started taking a closer look at the builders and as a

builders need some work.  One thing we've been getting alerted of is
memory usage, in particular less than 10% swap free.

We have a couple of options.

1) stop monitoring swap on the builders
2) reduce resolution on the builders (check less often and require more
failures in a row before notification, right now is 3 failures in a row
results in a notification)
3) increase swap (presently about 1G / core so between 2G and 8G of swap
on the boxes)
Some builders could really do with some more ram. but in the mean time perhaps up swap to 1.5g/core

I'd say a combination of 2 and 3 is going to get the best results of
improving reliability and reducing false positives
