  I did dladm add-aggr and its hung
• 15:39
  Smithx10
  tried killing it, nothing, pstack came up empty

  Do you have its process id?
• 15:44
  rmustacc
  Run mdb -k, and then '::pgrep dladm | ::walk thread | ::stacks'

  Well, there's your answer to where it is.
• 15:46
  rmustacc
  And why it can't be killed.

  I've seen this sort of thing a lot more on i40e, but ixgbe too?
• 15:59
  Smithx10
  do i just bounce it?
• 16:01
  danmcd
  I might have a little-hammer solution. Hang on...

  I found this out indirectly from (I think) Jerry J.
• 16:03
  danmcd
  It forces ZFS to free, which *should* free up large chunks of contiguous that devices like i40e (and apparently in your case ixgbe) need.
• 16:04
  danmcd
  This should unclog ixgbe's quest for contiguous memory. Please report back with progress?

  @Smithx10 --> any luck?
• 17:47
  Smithx10
  Sorry about that, was pulled into a meeting
• 17:49
  Smithx10
  looks like its stuck at pwait
• 18:04
  Smithx10
  looks like it took awhile but is went away :)
• 18:10
  danmcd
  Gotcha. memory reclaim is always annoying.
• 18:24
  danmcd
  Smithx10: that script should be treated like a hammer (because other things will suffer when ZFS goes into a full-reclaim mindset).
