NetXMS Support Forum

Hello,

I am trying to run nxmc standalone version 5.2.8, and it runs and I can log in, but when I click the inventory and click on the netxms host the application quits with below error: core dump

I am using Raspberry Pi 5 with Raspberry Pi (aarch64, arm64) OS Debian Trixie and KDE Plasma, with default-jre:

java -version
openjdk version "21.0.9" 2025-10-21
OpenJDK Runtime Environment (build 21.0.9+10-Debian-1deb13u1)
OpenJDK 64-Bit Server VM (build 21.0.9+10-Debian-1deb13u1, mixed mode, sharing)

Please suggest what I can do.

Thank you,
Alex
