> I can see SharedPageLockTracker.structureNameToId.put() being called, but never remove() or clear().
> Naturally, this leads to memory leak. During 36d uptime, an 1.3G of total retained heap (keys, values and cells) were reached. This is unacceptable, it should have either TTL or max size to avoid using 1% of heap (20% in this case).
