Description
Hi,
We have a Rocky 8.9 / Lustre 2.15.4 client which has trouble running a particular large single-node MPI application, when its input/output files are stored on a Lustre 2.12.6 filesystem. We didn't see this when the client was running Rocky 8.8 / Lustre 2.12.9.
The application hangs at shortly after startup for a while, eventually terminating with an error. The application messages imply a failure during a Fortran OPEN or READ statement.
I see multiple messages such as the following in the client syslog:-
