Any ideas?
What is the sizing of your sawp device? e.g. zfs list zone/swap
The machines were configured with different swap sizes:
[root@A ~]# swap -sh
total: 159G allocated + 668M reserved = 160G used, 49G available
[root@B ~]# swap -sh
total: 101G allocated + 95M reserved = 101G used, 30G available
After adjusting B's swap the timeouts are gone.
Thanks,
