Package: base Severity: normal
I am running Debian squeeze on my Qnap TS-119PII. I used the installer by Martin Michlmayr (cyrius.com). No exotic packages installed, just the ordinary openssh, samba, afp and apache. All seems to run fine until, once or twice a day, the systems crashes, rendering it unreachable on all ports (even ping). I am often pumping lot's of files in it through samba, but I am not sure that is the cause of evil here.

unfortunately it doesn't happen during a specific action, all the time. I installed debian, with /home being a separate partition, just openssh, samba, afp and apache2 installed. Copying files through samba for hours fine until, at some undefined moment in time the box stops all external connections and will not accept new once. No red lights or beeps. Reboot seems the only option. At least it did write to log... I tried the same recipe with a different hard drive: same cake. #./ver_linux If some fields are empty or look unusual you may have an old version.
