Debian 12 64 bit client stops communication

Post by hochsaler »

I have Asustor 6202T with latest ADM revision. I created a new VM in VirtualBox and installed Debian 12 (and did all updates) freshly. The reason is, that I installed also a document management system which is available for Debian 64 bit.

After starting the VM everything works fine for maybe 10 or 15 minutes. After that I loose all connections to the VM. This includes RDP (xrdp is installed in the Debian VM), SSH which I used for a command line to check for updates and the like and even ping which I ran in a terminal on the host machine. However, VirtualBox itself seems to be still connected to the VM. For instance, I can shutdown the VM by sending ACPI shutdown. After restarting the VM everything works fine again for a certain time, then stops again. It makes no difference when I start the VM headless.

Since the Debian VM should be a server for the document management system only and run permanently I didn°t install any other software packages. The VM is configured with a static IP address, host system and VM are in the same local network.

Any ideas?

Now I made a complete new installation of a Debian VM - and suddenly it works. The VM is running now since two or three days already. It is responding every time immediately when I connect via RDP or SSH. However, I didn´t figure out what is different compared to the first installation.
