Comment (by iwakeh):

 Steps to reproduce (from #18910, the discussion should take place here):
 [https://gitweb.torproject.org/user/iwakeh/collector.git/commit/?h=task-18910
 -first-sync&id=5eb89c10a0a720c1fa4eb806e5d5b5f2dee75b65 Collector branch]:
 Run the jar in a new location, i.e. with empty recent and out. Configure
 relaydescs and sync. RunOnce will be sufficient the OOM heap dump contains
 very many Reference objects. (Your assumption in one of the previous
 comments hinted in the right direction, I think, but I couldn't verify
 that yet.)
