From the message, and given that you were setting importances via usimbs.f, it seems that you have gone too aggressive in the biasing and you have filled the emf stack.
This means that you set a step biasing split that was much bigger than the attenuation for your electrons and photons through your shielding. As a result, the population of electrons and photons was growing larger every step, and you filled the memory.
Reduce the parameter by which you bias. Normally you would want to set that parameter so that the population of your particles of interest stays more or less constant.

Subject: [fluka-discuss]: user biasing using usimbs.f *** Doeimb: importance splitting not performed for missing room, in Emf stack ***
Hello everyone,
I have been trying to do biasing via usimbs.f. It has taken me few days of trial and error. I think I have fixed few issues (one of which resulted in a core dump).
Now, I am seeing the following message repeated ad nauseam in the .err file. What does this message mean and how can I go about fixing it?
*** Doeimb: importance splitting not performed for missing room
in Emf stack ***
Thanks in advance,
Mina
