I am getting very similar errors, running cesm1.2(rel06) using compset FMOZSOA(ne30_ne30). A sample of my "QNEG3" errors is shown below. I'd also appreciate any insight into this problem!  QNEG3 from chemistry/NH3:m=106 lat/lchnk=   6352 Min. mixing ratio violated at  141 points.  Reset to  1.0E-36 Worst =-1.0E-12 at i,k=   6 24 QNEG3 from chemistry/H2O2:m= 17 lat/lchnk=   6336 Min. mixing ratio violated at    1 points.  Reset to  1.0E-36 Worst =-2.3E-12 at i,k=  11 26 QNEG3 from chemistry/SO2:m=103 lat/lchnk=   5624 Min. mixing ratio violated at    7 points.  Reset to  1.0E-36 Worst =-5.9E-12 at i,k=  11 24 QNEG3 from chemistry/HNO3:m= 11 lat/lchnk=   6344 Min. mixing ratio violated at    7 points.  Reset to  1.0E-36 Worst =-1.2E-12 at i,k=   3 13 QNEG3 from chemistry/H2O2:m= 17 lat/lchnk=   6344 Min. mixing ratio violated at    7 points.  Reset to  1.0E-36 Worst =-2.9E-12 at i,k=   4 26 QNEG3 from chemistry/SO2:m=103 lat/lchnk=   6344 Min. mixing ratio violated at   12 points.  Reset to  1.0E-36 Worst =-1.4E-11 at i,k=   3 26 QNEG3 from chemistry/H2O2:m= 17 lat/lchnk=   5449 Min. mixing ratio violated at   10 points.  Reset to  1.0E-36 Worst =-1.4E-12 at i,k=   2 25 QNEG3 from vertical diffusion/NH4NO3:m=108 lat/lchnk=   5449 Min. mixing ratio violated at   46 points.  Reset to  1.0E-36 Worst =-1.6E-11 at i,k=   2 26 Setting mpi info: striping_factor=16 Setting mpi info: striping_unit=1048576 pio_support::pio_die:: myrank=          -1 : ERROR: pionfwrite_mod::write_nfdarray_double:         234 : Cannot send after transport endpoint shutdown--------------------------------------------------------------------------MPI_ABORT was invoked on rank 1 in communicator MPI_COMM_WORLDwith errorcode 1. Thanks,Marie
