I guess you just changed the title? > ZkUnderreplicationManager can build up an unbounded number of watchers > ---------------------------------------------------------------------- > > Key: BOOKKEEPER-1098 > URL: https://issues.apache.org/jira/browse/BOOKKEEPER-1098 > Project: Bookkeeper > Issue Type: Bug > Components: bookkeeper-auto-recovery > Reporter: Samuel Just > Assignee: Samuel Just > Priority: Minor > Fix For: 4.5.0 > > > getLedgerToReplicate leaves watches each time it traverses the > tree until it finds a suitable replication target. Since we don't have > a way of canceling watches, these watches tend to get abandoned, > particularly on interior nodes, which aren't changed much. Thus, > over time, some nodes would build up a very large number of watches. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
