Thanks for the quick response Mike - looking forward to 5.4.11. We'll upgrade to that once it's out!
Here's the info about what we're running on our t2.medium AWS instance > Ubuntu 14.04 w/ Linux 3.13.0-107-generic #154-Ubuntu SMP Tue Dec 20 > 09:57:27 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux > > From the output of ps, I can see that it's running Java > from /usr/lib/jvm/java-7-openjdk-amd64, which seems to be: > > ubuntu@hs2:~$ /usr/lib/jvm/java-7-openjdk-amd64/bin/java -version > java version "1.7.0_121" > OpenJDK Runtime Environment (IcedTea 2.6.8) (7u121-2.6.8-1ubuntu0.14.04.1) > OpenJDK 64-Bit Server VM (build 24.121-b00, mixed mode) Do you think it would make a difference to run oracle java? Finally, we're going to increase the java heap size from the default 1GB to 2GB via JVM_MAX_HEAP_SIZE. Also - I've noted that the t2.medium instance type is burstable...meaning when we hit this high CPU problem, we exhaust our Amazon CPU credits. We'll move this to a non-burstable instance type and see if when not limited by CPU credits the machine is able to recover from the high cpu.
