As I mentioned in a previous entry, we have been experiencing the same very intermittent error for both pw.x and ph.x . We have no ideas about the origin except that it seems to be related to the version of the openmpi library. For 3.1.1-intel-2018 and 3.1.0-intel-2018 the error is rather frequent. For 2.1.0-intel-2018, it seems to happen less frequently. It appears for QE 6.2.1 and 6.3. Unfortunately, it does not appear for very short jobs, but I will be happy to provide a sample input file for an intermediate size job if that will be helpful..... Thanks, Natalie
