Hi all, I've a couple of this machines [1] in a prduction environment. I suffer random reboots without any clear reason. A possible power failure it's a discarded point: I use a switched rack PDU and anything is showed by the logs. Moreover, I'm talking about datacenter environment, so there're a lot of redundant UPSs too. So, I tend to think it should be a hard/soft conflict, but when I check the dmseg and others logs after a random reboot, all appears completely normal. I know that a kernel dump will be great help, but this boxes has a 4/8GB of RAM, and their /swap is lesser. Moreover, I have a lot of services in the boxes: http/https (Apache), SMTP (Postfix), POP/IMAP (Dovecot) and database (MySQL). This point makes too complex to determines what is the origin of the random reboots. I have to say that the strange reboots seems that hasn't direct relation with the system load: they occurs randomly in stress or calm situations. I've looked at ACPI issues, but, accordint to this helpful info [2], all seems ok. ¿Some idea?
