I think I published the source code of my jamm plugin for Jenkins. It's not perfect yet, which is why I haven't released it, but you could install it and add the column to a view so you can identify the memory usage of your jobs.
Beware the perf impact of the column, so put it in a non-default view. Some other culprits: Are you using gerrit? The way gerrit uses the git plugin causes the branch information to grow and grow in every build until each build has multiple megabytes of branch info. There is an open bug, but I think the fix will be to move to multibranch which is a better fit. Are you running pipelines where the pipeline script was written by a groovy fanboy who has encoded lots of the build logic in the pipeline script? Besides being a bad idea - developers now need to use Jenkins to do a local build - it may interact poorly with the CPS transformation and create lots of flow nodes. There are probably other things to look for but off the top of my head (and on a phone at the side of a cold GAA pitch supporting my son) this is what I've got.
