zfs discuss - Feb 2011 - Investigating a hung system

Hi,

I''m investigating a hung system. The machine is running snv_159 and was
running a full build of Solaris 11. You cannot get any response from the 
console and you cannot ssh in, but it responds to ping.

The output from ::arc shows:
arc_meta_used             =      3836 MB
arc_meta_limit            =      3836 MB
arc_meta_max              =      3951 MB

Is it normal for arc_meta_used == arc_meta_limit?
Does this explain the hang?

Thanks,
Mark

It means that it has cached as much metadata as it''s allowed to during
the current circumstances (arc size).

No..
