Crash on the calculation of excited state with ADC(2)/COSMO
« on: January 11, 2018, 06:55:10 pm »

I'm using TM6.6(don't have a higher version) to calculate the excited state energy and oscillator strength with ADC(2)/COSMO/def2-TZVP. But I have one problem.
It always crashes when the ricc2_omp to calculate the part of  "CALCULATION OF COUPLED CLUSTER RESPONSE PROPERTIES", and there is no error information on the ricc2.out file. And if I restart the ricc2 calculation or do a new calculation from dscf, it will crash at the same point.
And sometimes on the error file of system, I can find this information:"bin/em64t-unknown-linux-gnu_smp/ricc2: line 39: 30867 Segmentation fault      (core dumped) $TURBODIR/bin/`sysname`/ricc2_omp ", but this error doesn't  always appear when crashes. Most time there is no any error information in the system error file.

I think there is no mistake in my input file, because I changed the basis set to def-SV(P), and ricc2 ended normally. And, in the gas phase, there is no problem.

This is the last part of ricc2.out:

Looks like a problem with the stack size. Check that your job can create a sufficiently large stack in the OMP-parallel parts. What is sufficient depends on the system size. Yours is quite large. Might need something like 1 GB.
