jvrao opened a new issue #1664: Scheduled SpeculativeReads are not getting canceled URL: https://github.com/apache/bookkeeper/issues/1664 Is this a question, feature request, bug report, or bookkeeper proposal? **QUESTION** **BUG REPORT** 1. Please describe the issue you observed: If configured, every read request schedules a Future task to send speculative reads on speculativeReadTimeout. When the read is completed successfully, this task must be canceled otherwise it leads to memory consumption and under heavy load the tasks get accumulated which forces lengthy GC cycles. These lengthy GC cycles may cause ZK lease expiry and all other sorts of problems eventually resulting in application errors.
