If your seeing swap_pager warnings it indicates two things:-
1. Your seeing memory pressure
2. Something is causing significant delay on transations to disk.
Additional information which maybe useful:-
* mptutil show adapter
* iostat 1
* Capture from top when the system is hung
Regards
Steve

Subject: Re: ZFS crashing while zfs recv in progress
I've put swap on a seperate disk this time and re-run the zfs send / recv, but i'm still getting the problem. Whats interesting
is, i'm still getting the same output about swap space on the console:
swap_pager: indefinite wait buffer: bufobj: 0, blkno: 36, size: 24576
The System is running from zroot and i'm trying to transfer to tank. zpool Status output:
