Fix HeapDumpOnOutOfMemoryError

✅ Solution

"HeapDumpOnOutOfMemoryError" in Logstash usually means the JVM ran out of memory due to excessive data processing or plugin memory leaks. To fix this, increase the JVM heap size in the jvm.options file (e.g., -Xms4g -Xmx4g) and carefully review Logstash configurations and plugins for memory-intensive operations or potential memory leaks. Reducing the number of filters, optimizing grok patterns, or using more efficient plugins can also alleviate memory pressure.
