We have a Cisco Systems Inc R200-1120402 (2xE5540, 64GB of ram,

The server stops responding, the console freezes and we can't ssh into
It did panic once with ""panic message: I/O to pool 'zones'
appears to be hung" but has locked up twice since with no panic msg.
I'm wondering there is something between 20151104T185720Z and
20160317T000621Z that might explain the problem?
The fact that you have the I/O deadman fire is not always a good sign.
That suggests that for some reason I/O has stopped. When this happens,
are you able to inject an NMI (non-maskable interrupt) into the system?
You can do this via the 'chassis power diag' ipmitool command.
That should force it to generate a dump and we can talk through how to
investigate what's going on there.

Just read this email now. I will follow
https://wiki.smartos.org/pages/viewpage.action?pageId=754743 the next
time it happens.
I have been able to get some stability by freeing up ram on this
particular system.

Previous zonememstat were 20GB higher.
So far, we have seven days of uptime.
I'm also wondering about how at what number to set the CAP. I thought it
was linked to vmadm update UUID ram= but that doesn't seem to be the case.
