magic number wrong

[Mary Ann Lipa]

hi,
is this message a threat?
i am seeing this on dmesg, but i cant find it on syslog.log and on any LVM related devices/filesystems...
is it safe to reboot my server?
thanks!

The entire message would help. A bad magic number normally means that an executable for a mismatched platform is trying to execute and failing. For example, you might be trying to execute 64-bit code on a 32-bit processor (or even the wrong processor family) but this could be a programming message that a data file contains invalid checksums. There are just not enough data to know.

Hi,

here magic number wrong means there is a discrepancy between the kernel booted and the present kernel located in the file /hp-ux. i.e. If you have modified the kernel and have not yet rebooted the system. Reboot the server in attended mode, but before that make sure you have a working kernel...

Cheers!!!
