Some HP hosts may reboot automatically if the system uptime is more than 400 days

Our HP UX version is HPUX11i-OE-Ent B.11.11.0509, the hardware is most about HP RP4440, and some of them is HP RP5470.

In customer side, we found Some HP hosts may reboot automatically if the system uptime is more than 400 days, how to resolve this problem? Please help to give the solution and the reason. Thanks.

>>Some HP hosts may reboot automatically if the system uptime is more than 400 days,

That makes absolutely no sense. Uptime itself should have nothing to with when a system reboots.

However, there may be other extenuating circumstances that cause. Have you had HP examine a crash dump? What do /etc/shutdownlog, /var/adm/syslog/OLDsyslog.log, /etc/rc.log.old show?

Are there application issues if the app stays up for too long? Is memory an issue?

>>how to resolve this problem?

Call HP next time it happens and work with them.
