[Wien] lapw2c tries to read an anomalous amount of data

[Luc Fruchter]

I think it is unlikely related to a specific machine or OS problem: I 
encountered the same situation with different machines types, different 
OS (Redhat Sci. Linux, Ubuntu), different Intel compilers versions (from 
2017 to 2019). But it could be some common configuration problem.

I don't use mpi, and yes there four 9.6 Gb .vector files (there is 4 
CPUs used), the total of which exceeds the total memory (24 Gb), while 
the four lapw1 processes only used 20 Gb.

I still have to figure out what is the memory needed for lapw2s, even 
when it is sufficient for lapw1s. I will try to reduce the number of 
CPUs, to see if the total .vector files size is the problem for lapw2s.
