--- Comment #180 from Eric Benoit (eric@...s.ca) ---
I've been able to reproduce the issue on the other workstation I'd mentioned
earlier with ZFS:

NAME                        STATE     READ WRITE CKSUM
nipigon                     ONLINE       0     0     0 
  mirror-0                  ONLINE       0     0     0 
    wwn-0x5000c5006407e87e  ONLINE       0     0    17 
    wwn-0x5000c5004e4e92a9  ONLINE       0     0     6 

This isn't particularly hard to trigger; just a bunch of files filled with
/dev/urandom (64M*14000) being read back concurrently (eight processes) over
about 90 minutes.

Kernel version is 4.19.6 compiled with gcc 8.2.0 (Gentoo 8.2.0-r5 p1.6).

Have we any other ZFS users experiencing this?
