OR eigensolver+BFGS geo_optimizer error

[eft rsd]

Hi all,

I've been using the OT[CP2K(2.4)] eigensolver successfully for calculating 
energies for quite large systems (60-70 atoms) and now I need to find the 
optimized geometry using BFGS with OT (attached 3.inp). But I get the 
following error message:


  
 *************************************************************************
 *** 20:24:42 ERRORL2 in cp_dbcsr_cholesky:cp_dbcsr_cholesky_decompose ***
 *** processor 0  :: err=-300 condition FAILED at line 123             ***

            1 CP2K


However, when I constrain all atoms in the large system I do not get this 
error and the calculations go OK.  Changing the solver to Digonalization 
proceeds on successfully (attached 1.inp), but I would like to use OT 
throughout for its fast performance. I tested the combination OT+BFGS for 
the small system of H2O (attached 2.inp), with and without pinning the 
atoms, and that worked fine: so why doesn't work for the large system? 
Please help me figure out where the problem lies. 

Thanks,
ER
