Can you show the output of ^T? Can you enter crash(8) or ddb and get process listings and stack traces? ps ps/w bt/t 0t1234 (if du pid is 1234) and bt/a ffff1234... for anything that looks relevant in ps and ps/w output. (I might suggest followups depending on what ps and ps/w say.) > > I recently fixed a number of races and other issues in dk(4) in HEAD > > (and have some changes upcoming to fix more).
