Post-release analysis of high memory usage:

  • Excess anonymous functions/lambdas created, specifically faster than they could be acted on. Resolution: Fixed in #1444
  • Unbounded bootstrapping process that could download state blocks to memory. Resolution: Fixed in #1448
  • Vote and Block deduplicator (uniquer) never cleaned up cached copies of votes or blocks. Resolution: Fixed in #1473

This was tracked down almost entirely to connection tracking functions being generated, fixed in #1444.

There were a few other causes, but they have also been addressed at this point.
