https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=194513 --- Comment #3 from James Van Artsdalen <james-freebug@jrv.org> --- Created attachment 149075 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=149075&action=edit procstat -kk -a The same systems hang the same way on "zpool history", although the attached EATMEM does not seem tp help. Attached is the full "procstat -kk -a" output with a "zpool history" stuck.
