I have a tricky problem with memory protection. I am not able to start some programs because of the problems with some libararies. I run into a "cannot change memory" issue.
I mapped the user home to a filepath on a GPFS (126.96.36.199) filesystem. When I map the path via NFS the error didn't occur. ( I was not able to reproduce it). I am at my wit's end. I am note sure if Ubuntu is the one to blame or the mounted gpfs filesystem.
Mainly the error occure when I work with an activated Python environment or working with idl, more specifically, when I try to load shared libraries (*.so) in the user space
user@server:~$ source activate py34 (py34) user@server:~$ python python: error while loading shared libraries: libpython3.4m.so.1.0: cannot change memory protections user@server:~/path$ idl IDL Version 8.5.1 (linux x86_64 m64).

Infos about the Server:
NAME="Ubuntu" VERSION="18.04.2 LTS (Bionic Beaver)" Kernel=4.15.0-45-generic
What can be the reason?
