Hello, once I had hardware failures on my E250 server which I was able to reproduce also under Solaris. This enabled me to bother the Sun support. Now I am in trouble because the problem only occures under Linux :-(.
After the crash I had to switch on the machine manually. A can't to anything via serial line (seyon). It does not take any signal (at least 'Break' does not work and I did not found any other signal to realive the box). The test program is fairly simple: #!/bin/bash i=0 while [ $i -lt 1000 ] ; do echo $i let i="$i+1" dd if=/dev/sda4 of=/dev/null done This is the output (Sorry for the German locale. I translate: dd: Reading of »/dev/sda4«: Input-/Output Error ) 0 dd: Lesen von »/dev/sda4«: Eingabe-/Ausgabefehler 4191936+0 Records ein 4191936+0 Records aus 1 dd: Lesen von »/dev/sda4«: Eingabe-/Ausgabefehler 4191936+0 Records ein 4191936+0 Records aus 2 dd: Lesen von »/dev/sda4«: Eingabe-/Ausgabefehler 4191936+0 Records ein 4191936+0 Records aus 3 dd: Lesen von »/dev/sda4«: Eingabe-/Ausgabefehler 4191936+0 Records ein 4191936+0 Records aus 4 dd: Lesen von »/dev/sda4«: Eingabe-/Ausgabefehler 4191936+0 Records ein 4191936+0 Records aus 5 This was the last message from my box.

It happens at least with 2.4.16 and 2.4.17. Whatever problem /dev/sda4 has - the machine should not crash, shouldn't it? I tried the analogous script on /dev/sdd where I have a Solaris test partition. At least I tried it with a partition at /dev/sdd, because I do not know which is the syntax under solaris to adress exactly the physical /dev/sda4. Any ideas to get the machine working again? What additional information is needed to track down the problem? Kind regards Andreas.
