Also once you've got your phi_convict_threshold sorted, if you see these again
check:

AWS does occasionally have the odd increased latency issue / outage.

Has anyone experienced network i/o issues with ec2? We are seeing a lot of
these in our logs:
HintedHandOffManager.java (line 477) Timed out replaying hints to
/10.0.x.xxx; aborting (15 delivered)
and these...
Cannot handshake version with /10.0.x.xxx
and these...
java.io.IOException: Cannot
It's a good idea to increase phi_convict_threshold to at least 12 on EC2.
Using placement groups and single-tenant systems will certainly help.
Another optimization would be dedicating an Enhanced Network Interface (

specifically
