Lawrence,
So I was running large transient VI simulations and was noticing that each time level was getting slower and slower. I knew the equations were getting harder to solve but wasn't sure if it was also because of a memory leak. Turns out it was mostly the former, although at the time it was actually a combination of both because I noticed that the memory consumption per Ubuntu activity monitor was increasing. I wasn't efficiently implementing some python and UFL functions
As of now I don't think I am experiencing anything, so this was more of a hypothetical situation in case it happens again.
So we have definitely in the past observed some issues with memory leaks in transient simulations. But I think I managed to squash them all. However, if you have something that exhibits memory growth, then it would be interesting to see, because it may be that we still have a bug in this area. Lawrence
