#3895 closed defect (worksforme)
Memory leak in the Linux simulation executable when using KLU

Description
The simulation of our larges network models (with 100k implicit linear equations) cause a memory leak of about 1 MB/s. Although tolerable, this should probably be fixed, because you eventually run out of memory, for very long simulations.
Replaces #3646.

Milestone moved to 1.12.0 due to 1.11.0 already being released.

The milestone of this ticket has been reassigned to "Future".
If you think the issue is still valid and relevant for you, please select milestone 1.13.0 for back-end, code generation and run-time issues, or 2.0.0 for front-end issues.
If you are aware that the problem is no longer present, please select the milestone corresponding to the version of OMC you used to check that, and set the status to "worksforme".
In both cases, a short informative comment would be welcome.

This bug is hard to reproduce. valgrind says there is no memory leak related to klu (as far as I can tell); has this been fixed?

This was an old bug when we ran our first large grid model experiments, and was probably fixed a long time ago. I will run a large batch of tests as soon as Complex numbers are supported by the new front end; I will re-open the ticket if there are still problems.
Ticket retargeted after milestone closed
