System > Memory Utilization

Under the current memory stats are various charts with the heading "Memory usage history". The requests to populate these charts are returning 500 errors. These charts did work, this behaviour is new.

Recent changes to our setup:

1. Update to OpenJDK Runtime Environment 1.8.0_144-b01 OpenJDK 64-Bit Server

2. Update to Apache Tomcat/8.5.20

Probe version 3.0.0.RC2
