Dead Particles that are properly rendered in the viewport are not being rendered using F12. This Bug occurs with Eevee, Workbench and Cycles render engines.

Confirmed, checking...
#59272.blend
Hm,
make_duplis_particle_system()
seems to be making duplis for dead particles inDAG_EVAL_RENDER
as well asDAG_EVAL_VIEWPORT
...Not sure yet why these are not actually rendered, needs further investigation...

I still have same problem. Pls tell ıf there is any progress..
Added subscriber: @BacMan12
Also encountered this today. Would be nice with a fix but particle nodes is coming, so it will probably be fixed then...hopefully.
Added subscriber: @Jeroen-Bakker
Seems depsgraph related.
When rendering the particles that aren't born are already visible
In viewport the particles that are dead are still visible.

The dead particles are being re-spawned on the emitter as they die. I did some trouble-shooting on this, comparing 2.79 to my current version. I'm currently using 2.81.16. .
I created the setup as described in the above original post in 2.79. All works properly.
I then saved the scene and reopened it in 2.81. It still rendered correctly.
I then created an identical particle system in 2.81 next to the imported 2.79 system. The 2.79 particles rendered ok, but the 2.81 particles did not.
If I change the 2.81 emitter to the 2.79 particle setting, it still does not render correctly.
If I change the 2.79 emitter to the 2.81 particle setting it still renders correctly.
I tried breaking the 2.79 particle emitter, and the only way I could do it was to change the number of particles emitted. Then it will not render properly, Undoing the change will correct the render.

great work, had the same problem. precisely the issue, i can only add a work-around, more of a kludge. for still images at least you can "convert to mesh". i used it for a metaball particle soup and it worked, haha. thanks again.

Arrow Rain Test.blend
I struggling this issue. I tried in 2.83.7 and 2.90.1. But result is the same. This attached project is almost similar to which I want to create an arrow rain scene. Dead particles still not showing in the render.
Added subscriber: @RMENON
I encountered this issue today in 2.90
Encountered what i believe to be the same issue in 3.6.4
On further examination, there was merely a discrepancy between viewport and render, somehow caused by a low cache step size. This may be something worth looking into.
In the file in question, I have an emitter several thousand units above the killer platform.
