Proxmox uses a somthing modified RHEL6 2.6.32-x kernel. This kernel was introduced with new Proxmox version 1.9.

But with the switch from older 2.6.32-x based Squeeze kernel to the RHEL kernel many user report strange JVM errors inside their OpenVZ container in context with Java web applications (JBoss, Tomcat, etc.)
- JVM crashes after a while
- JVM consumes 100% CPU
- WepApps is alive, but stop handling HTTP request.

Switching back to the older kernel solves these strange errors

Has someone similar problemes with Java (web-based apps) and the original RHEL based kernel?
