Thank's for your quick answer!
I can't use ipmi in this machine...
# ipmitool sel Could not open device at /dev/ipmi0 or /dev/ipmi/0 or /dev/ipmidev/0: No such file or directory Get SEL Info command failed
# modprobe ipmi_si FATAL: Error inserting ipmi_si (/lib/modules/2.6.18-194.26.1.el5xen/kernel/drivers/char/ipmi/ipmi_si.ko): No such device
# lsmod |grep ipmi ipmi_watchdog 52641 0 ipmi_devintf 44753 0 ipmi_msghandler 73369 2 ipmi_watchdog,ipmi_devintf
This is a Virtual Server from 1and1, I cannot access the BIOS...
any other idea?

Hi to all!
We're using CentOS 5.5 64bits for our Plesk 11.
This week we had the following problem 3 times...
Suddenly, the server stops responding in all services (SSH, Apache, Postfix, ...) but ping works!
After wait a few minutes (or 2 hours some times) the server continues unresponsive until we reboot. After reboot we search on /var/log/messages but cannot find useful information...

A quick google shows me that the postfix messages are just that, and you might want to fix it so it's not asking for it.
HOWEVER, the important thing is that it appears to have just gone completely unresponsive. I've seen that happen to some servers here, and we've never found any clues.... On the other hand, IIRC, they tended to be boxes that we've had other problems with, and have had a number rebuilt under warranty (mostly Penguins, and the problems I've had with them, as they're all Supermicro m/b's, told me to NEVER buy a Supermicro m/b).
The only thing I can suggest trying might be to use ipmitool (assuming you don't want to bring them down and look in the BIOS) to read the SEL (system event log), to look for hardware errors.
