vmstat hang on Sol10 on Niagara

we have several Niagara box running Solaris 10 with vxvm 4.1. The vmstat hang for very long time before give output.

Using truss with vmstat, I found vmstat looping on :

-

stat("/dev/osa/dev/dsk", 0xFFBFF620)Err#2 ENOENT

stat("/dev/dsk", 0xFFBFF620)= 0

stat("/dev/md/dsk", 0xFFBFF620)Err#2 ENOENT

stat("/dev/rmt", 0xFFBFF620)= 0

open("/devices/pseudo/devinfo@0:devinfo", O_RDONLY) = 4

ioctl(4, 0xDF82, 0x00000000)= 57311

ioctl(4, 0xDF07, 0xFFBFF22C)= 5567640

ioctl(4, 0xDF80, 0x004C0000)= 5570560

close(4)= 0

I am not sure what it is doing. What vmstat waiting for?

"/dev/osa/dev/dsk" and "/dev/md/dsk" do not exist.
