:If you do have 8gigs of swap, then you do need to increase the parameter..
:The default is 7.7gigs of supported swap... (assuming that struct swblock
:hasn't changed size... The maxswblock only limits it... If swap is more
:than 8x memory, then changing kern.maxswzone will not fix it and will
:require a code change...

The swblock structures only apply to actively swapped out data. Mark,
how much data is actually swapped out (pstat -s) at the time the
problem is reported?
If you can dump UMA memory statistics that would be beneficial as well.
I just find it hard to imagine that any system would actually be using
that much swap, but hey! :-)
