QM call was not successful with OpenMolcas

[Yuanypu]

Hello,

I was running some OpenMolcas+Sharc calculations with CASPT2 method. The trajectory stops at timestep 34 (17fs) with the error message: QM call was not successful, aborting the run. Error code: 19968. The calculations were carried in a cluster, so the QM files in the scratch directory were deleted. I was wondering what causes the error and where I should check the meaning of each error code. Many thanks!
