When we remove a peer, we try to shut > down all threads gracefully. But, under certain race condition, the > underlying executor gets shutdown and the CompletionService#take will block > forever, which means the remove_peer call will never gracefully finish. > Since ReplicationSourceManager#removePeer and > ReplicationSourceManager#recordLog lock on the same object, we are not able > to roll WALs in such a situation and will end up with gigantic WALs. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
