Full GC in JVM is crucial for memory management but can severely impact application performance due to high CPU consumption and application thread pauses. Consecutive full GCs typically indicate insufficient heap size allocation. Solutions include increasing JVM heap size, enhancing Perm Gen/metaspace size, or adding more JVM instances. Validation is essential.
I had this interesting problem with a major shipping/logistics company. Their application was running on Java 6, JBoss Cluster in RedHat Linux platform.
