> SYNOPSIS: ps hangs without output or header
> 
> DETAIL DESCRIPTION:
> 
> 
> In Solaris 2.X:
> 
> Sometimes, after an abrupt system crash, bd.off becomes a 
> link to nowhere. When this occurs, the ps command hangs 
> without displaying the header or the process data.
> 
> @ 16: ls -l bd*
> lrwxrwxrwx   1 root     root          11 Nov910:59bd.off ->
> 
> Note:
> 
> If ps is used in the .login script, or is part of the boot process,
> it can appear as though the system is hung.
>
> SOLUTION SUMMARY:
> 
> 
> The bd STREAMS module processes the byte streams generated
> by the SunButtons buttonbox and SunDials dialbox.
>
> If ps is hanging without output, go to /dev 
> and remove bd.off. Then boot -r and the problem should be 
> corrected.
> 
> After the boot -r, the correct link will be re-established:
