RaulGracia commented on issue #2269: Bookie shutdown due to OutOfDirectMemoryError URL: https://github.com/apache/bookkeeper/issues/2269#issuecomment-593888409 @aloyszhang @eolivelli I have seen this problem as well. In our case, we have prevented this from happening by using `InterleavedLedgerStorage` instead of the default one (`SortedLedgerStorage`), as it does not contain `EntryMemTable` objects that seem to use significant amount of memory (tested with Bookkeeper 4.9.2). Of course, this decision comes at the cost of read performance, but in our case we can afford it, as we only read from Bookkeeper for recovery after a crash. Since we shifted the ledger type, we have not seen more memory issues like this.
