If you receive a notification message about an unexpected error message,
check the Failover Manager log file for an
message. Failover Manager runs with the default memory value set by this
# Extra information that will be passed to the JVM when starting the agent. jvm.options=-Xmx128m
If you are running with less than 128 megabytes allocated, you should increase the value and restart the Failover Manager agent.
Failover Manager is tested with OpenJDK; we strongly recommend using OpenJDK. You can use the following command to check the type of your Java installation:
# java -version openjdk version "1.8.0_191" OpenJDK Runtime Environment (build 1.8.0_191-b12) OpenJDK 64-Bit Server VM (build 25.191-b12, mixed mode)
