Bad DM normalization happens

Dear all,

I got the problem during the calculation, got an error messege "Bad DM normalization: Qtot, Tr[D*S] = 1142.00000000 1141.82007575" in one of two machines.

Here is one more things. In Computer 2, it runs normally if i use "Diag.ParallelOverK T" option. (But it runs very slowly)
Do you have any comment?

Compile options are the same, but used different version of Intel compiler and mkl. (arch.make file is below)

Computer 1: (No error)
CPU: (I don't know the model, but it is 4 years old computer, so it is not "scalable CPU")
OS: CentOS 7
Compiler: Intel Parallel Studio 2019.3.199

Computer 2: "Bad DM normalization"
CPU: Dual Intel® Xeon® Scalable Processors (Gold 6130(22M Cache, 2.1 GHz, 16cores))
OS: CentOS 7
Compiler: Intel Parallel Studio 2018.5.274

2. arch.make

arch.make file is below. arch.make files in two computers are the same, except version of intel compiler and mkl.
