> we found that replaying entries of deleted ledgers would exhaust ledger
> cache. then ledger cache would no clean page to grab, it would throw

> {code}
> java.util.NoSuchElementException

> org.apache.bookkeeper.bookie.LedgerCacheImpl.putEntryOffset(LedgerCacheImpl.java:165)
> {code}
> this issue is because bookie grabs a clean page but fail to updating page due
> to NoLedgerException, but bookie doesn't return this clean page back to
> ledger cache. so the ledger cache is exhausted, when new ledger want to grab
> a clean page, it failed to find available page.
