Thanks for the tip! This was indeed the problem! Yes, I could reproduce the same behavior on different machines too. In each case, I used openmpi installed with `apt-get install libopenmpi-dev` . Based on your suggestion, I removed openmpi, and installed mpich also with `apt-get`, then recompiled both PETSc-SLEPc and FreeFem. This solved the memory leakage. Furthermore, now that I use mpich instead of openmpi, the programs do not start sleeping processes (these I mentioned in [this](https://community.freefem.org/t/number-of-processes-and-memory-usage/1551) post) . Moreover, I think my programs also run faster! Thanks for the help, I really appreciate it! --- _[View the full topic](https://community.freefem.org/t/sorting-out-memory-leakage/1745)._
