  JVM java 8 restart issue Resolving JVM restart issues in Java 8 follows a similar approach to the general JVM troubleshooting steps, but there are some specifics related to the Java 8 environment to consider:   1. Address Memory Issues: OutOfMemoryError: Java Heap Space:  This is a common reason for JVM restarts in Java 8 when the allocated heap memory is insufficient. Increase Heap Size:  Modify the  -Xms  (initial heap size) and  -Xmx  (maximum heap size) parameters to allocate more memory. Analyze Heap Dumps:  Enable heap dumps on OutOfMemoryError using  -XX:+HeapDumpOnOutOfMemoryError  and analyze them with tools like Eclipse MAT or VisualVM to identify memory leaks or objects consuming excessive memory. OutOfMemoryError: Metaspace:  In Java 8, PermGen (Permanent Generation) was replaced by Metaspace, which resides in the native memory. Increase Metaspace Size:  If you encounter  OutOfMemoryError: Metaspace , i...

JVM restart issue resolution To resolve JVM restart issues, consider the following actions:   1. Address Memory Issues: Increase Heap Size:  Insufficient JVM heap memory is a common cause of restarts, leading to  OutOfMemoryError . Increase the heap size (e.g., -Xms and -Xmx) to accommodate the application's memory requirements. Enable Heap Dump and GC Logs:  Configure the JVM to generate a heap dump on  OutOfMemoryError  and enable garbage collection logs for analysis to identify memory leaks or inefficiencies. Fix Memory Leaks:  Identify and fix memory leaks in your code where objects are not properly released, leading to increasing memory usage. Adjust Stack Size:  If stack overflow errors occur, increase the stack size using the  -Xss  parameter. Check for Native Memory Exhaustion:  If the JVM or application uses excessive native memory, it can lead to crashes. Troubleshoot JNI code for memory leaks.   2. Optimize Applicati...
