Steady increase in memory use when running createMdsMesh

[Thomas-Ulrich]

Hi,

I'm trying to generate large meshes (e.g. the one that I just generated had 657117285 tetra cells) with SimModeler. The SimModeler parallel generation uses ~150Gb of memory for 10 ranks. But when I then convert the mesh using this function: https://github.com/SeisSol/PUMGen/blob/master/src/input/SimModSuite.h#L183C19-L183C32 I can see (with htop) that the used memory steadily increases until reaching 880Gb. Could it be a memory leak? I'm using [email protected]

Thanks in advance, Thomas.

Sounds like it. Thank you for reporting. We'll run valgrind on a smaller mesh and see what it reports.
