Maven builds? On our install, we saw pretty much the same behaviour, which was down to slow disk, and memory pressure. Basically when memory gets short, things needed for the home view get binned, making the reload expensive. If you can do without them, rm -rf'ing the fingerprints directory and r

I know this sounds obvious, but did you do an upgrade recently? If so, what was the versions of Jenkins/plugins before? Differences in general? If possible, you might then want to do a git bisect to try and identify the offending commit(s). But sure, even more if 2 days are needed to reproduce the
