Suicidal dwarf?

Anyways, are you sure that water pressure didn't slam him against a wall and knock him unconscious?

I don't think so, his job was listed as "Sleep" and he had no visible injuries.

Haven't seen this in 31.08 since its very hard to do on demand, but I've seen it happen in 31.03.

Dwarf carved a fortification into the side of a brook. Water then began flowing into the plumbing system, but at a very slow pace. Not pressurized, and a dwarf can easily outrun the water.

The dwarf decided it was naptime and just laid down for a nap. He had no injuries at all, and the water filled up to 7/7 and he drowned without waking up.

Reproducing this will be very hard to do, since you need to time the task such that the dwarf wants to sleep right after finishing the task. If he doesn't do it right away then he won't be caught by the water and drown. Its a matter of luck getting the timing to reproduce the bug.

The fact that he suddenly went to sleep probably means he figured he couldn't path to his bed (or any bed) and instead decided to sleep on the ground.

Should be easy to reproduce, actually. Build a burrow deathtrap and confine a dwarf to it. When he goes to sleep, open the floodgates.

There were no beds in my fortress at the time, actually. Can't think of any reason he should have had pathing problems.

Had no beds in my fortress at the time either. If there are no beds dwarves will just snooze where they are.

I do think the idea of a burrow or meeting zone reproducing it would work. Make it two levels. Bottom level is the meeting zone. Have no beds. When dwarves get tired they will sleep on the floor. Slowly flood the meeting zone while at the same time allowing them to escape up ramps to dry ground.

The water should cause the dwarves to interrupt their sleeping to move to higher ground.

I can reproduce the "sleep on command" effect reliably if you want. (0000733)

1. create burrow
2. assign dwarf to dig
3. let dwarf start digging and PAUSE
4. assign dwarf to burrow

Result:
dwarf will finish the current task, aka. digging.
dwarf will then become "stuck" on a nearby tile for several minutes.
while stuck, dwarf will use this time to take a nap if he is tired at all.
