Hello everyone,

I recently encountered the frequent issue of Java crashing after some hours when I run OpenEMS Edge.

It runs on a Windows Computer with 16 GB Ram. So far I only start OpenEMS-Edge in Eclipse.

Here is the Error-Message:

```auto
#
# A fatal error has been detected by the Java Runtime Environment:
#
# EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x70721b9c, pid=9045800, tid=9203716
#
# JRE version: OpenJDK Runtime Environment Temurin-17.0.8+7 (17.0.8+7) (build 17.0.8+7)
# Java VM: OpenJDK Client VM Temurin-17.0.8+7 (17.0.8+7, mixed mode, emulated-client, serial gc, windows-x86)
# Problematic frame:
# V [jvm.dll+0x381b9c]
#
# No core dump will be written. Minidumps are not enabled by default on client versions of Windows

```

“Problematic frame” is always something different and can also be simple Exceptions because of a missing component.

Does anyone had same experiences? Does anyone has a clue what causes this error and how to solve it?

Many thanks in advance!

Regards  
Alex

Did you try running it with Java 21 as recommended?..

In the mean time I found that it only appears if windows RAM is almost full. Somehow windows fills its RAM over one week from 40% to almost 90%. When rebooting frequently it does not happen. I consider switching to windows server.

PS: Switching to Java 21 did not help
