java.lang.OutOfMemoryError: Compressed class space
Release : 9.4
Component : API GATEWAY
The Dynatrace was installed on gateway nodes.
The problem is gone after disable the Dynatrace one agent.
Disable Dynatrace entirely -- backup and remove file /etc/ld.so.preload (The dynatrace one agent is loaded for every process via the ld.so.preload)
# cat /etc/ld.so.preload
Alternately, if still want to use Dynatrace for monitoring, would need the Dynatrace expert to tune the Dynatrace until it doesn't impact the gateway.
