[12:19:03] Simulation instability has been encountered. The run has entered a
[12:19:03]   state from which no further progress can be made.
[12:19:03] This may be the correct result of the simulation, however if you
[12:19:03]   often see other project units terminating early like this
[12:19:03]   too, you may wish to check the stability of your computer (issues
[12:19:03]   such as high temperature, overclocking, etc.).
[12:19:03] Going to send back what have done.

it didnt even finish one step :eek:



edit: I just checked logs for other instances on that server and 2 days later (7/24) on p774 i got

and also on 7/18 on another instance running p774 - 24 frames into it ... same

So could it be Natural WU atom smashing errors or problems with the server ???

p775 is prone to instant EUEs. I wouldn't worry unless it starts to happen regularly on WUs other than p77x.
