that will be usefull with this panic.
I *really* need some solution :(
Any ideas ?
reclaim pages (8 times instead of once with a sleep in between the
attempts).
The idea is that pages may become available at some time during one
of the sleeps.
Just try it and see whether it helps. Can't do any harm.
After apply the patch the machine survives to 3 days of work, but
paniced again after the system start using swap because some
applications were using more memory, here is the panic message:

happier on one of the heavily loaded servers that I look after.
It also appears to prevent a deadlock under very heavy load - something
I've not yet had time to debug.
Try adding:
vfs.zfs.zil_disable=1
vfs.zfs.prefetch_disable="1"
to /boot/loader.conf
and let us know if it makes a difference.
Added now only
vfs.zfs.prefetch_disable="1"
I let you know the result.
Is the result promising?
