Hi Everyone,
It looks like entropy was OK; /proc/sys/kernel/random/entropy_avail was about ~3500 on
each vm. rngd was not installed.
However the issue went away around lunchtime of 2-Jan! It does not appear to be load
related as it is slightly higher now than when we were seeing those issues. We're
looking at the network now...
Thanks everyone, and Happy New Year :)
