When using scientific linux (only running Oracle XE 11gR2 or when running Oracle standard 11gR2), after an arbitrary amount of time (sometimes within seconds of start up, sometimes 2-4 hours later), the guest OS freezes (no GUI, no SSH, no DB connections). I have to kill the process and restart to get it to run. There are no issues with running Windows XP. Host is running with 2 CPUs and 64 GB of RAM. I have tried running the Guest with as little as 512 MB RAM and up to 4 GB RAM, and running with 1 CPU or 2 CPUs. " defect closed other VirtualBox 4.2.10 fixed guest freezes other other
