I am trying to calculate the raman spectra of a growing polyacetylene molecule. when I only have acetylene my calculation runs fine, but as soon as the molecule grows in size (10 atoms and more) I start getting all sorts of weird error messages.

For example:
------------------------------------------------------------------------
ssread: end of file reading from unit 67
------------------------------------------------------------------------
------------------------------------------------------------------------
current input line :
44: task dft raman numerical
------------------------------------------------------------------------
------------------------------------------------------------------------
An error occured while trying to read or write to disk space
------------------------------------------------------------------------
For more information see the NWChem manual at

For further details see manual section:


[0] Received an Error in Communication: (67) 0:ssread: end of file reading from unit:

In some other cases it just shuts down, no real error message whatsoever:

[cli_15]: aborting job:

TACC: Shutdown complete. Exiting.


I have seen also the appearance of this message popping up time and time again:
angular momentum value: 0 standard basis set name: "pcS-0"
input line that generated warning:
**** WARNING Zero Coefficient **** on atom " C"


After I saw these errors while using the basis set pcS-0, I figure I change it to aug-pcS-0 to see if the errors still persisted, but now instead I am getting errors like this one:
rtdb_seq_get: type mismatch "task:theory" in ./c16.db: arg=1000, db=1748661350
------------------------------------------------------------------------
task: no task input for theory? 0
------------------------------------------------------------------------
------------------------------------------------------------------------
current input line :
43: task dft optimize
------------------------------------------------------------------------
------------------------------------------------------------------------
An error occured in the Runtime Database
------------------------------------------------------------------------

For further details see manual section: 




[0] Received an Error in Communication: (-1) 0:task: no task input for theory?:

task: no task input for theory?                   0
...



The input file that I am using looks like this:
echo

start c4

title "TDDFT c4 BLYP/pcs0"

geometry units angstroms
load poly4.xyz
end

basis spherical
* library pcS-0
end

dft
xc becke88 lyp
direct
convergence energy 1d-8 nolevelshifting
tolerances tight
iterations 1000
end

hessian
thresh 1d-8
profile
end

property
response  1 8.8559E-2
damping 0.007
end

raman
normal
GAUSSIAN
end

driver
maxiter 30
xyz opt
end


task dft optimize
task dft raman numerical

freq
reuse
temp 1 0.0
end

task dft freq

I would appreciate any advise!

SOLUTION
Normally these types of errors occur when the jobs are not being properly run. Make sure that you are running an appropriate number of tasks per each computing node you are requesting, don't run to many on a single node for this reduces the available memory for each one of them.
Also, don't have multiple jobs reading and writing at the same time from the same files. This may happen for example, when dependencies are not properly setted up.
