Julian Reschke edited comment on OAK-5528 at 3/24/17 12:29 PM: --------------------------------------------------------------- bq. Are they any code dependencies that requires us to backport more changes? Good point. Turns out we should backport OAK-4859 first; I'll assume I can go ahead with that as it only affects logging. was (Author: reschke): Good question, will check. > leaseUpdateThread might be blocked by leaseUpdateCheck > ------------------------------------------------------ > > Key: OAK-5528 > URL: https://issues.apache.org/jira/browse/OAK-5528 > Project: Jackrabbit Oak > Issue Type: Bug > Components: core > Affects Versions: 1.4, 1.5.14 > Reporter: Stefan Eissing > Assignee: Julian Reschke > Labels: candidate_oak_1_0, candidate_oak_1_2, candidate_oak_1_4 > Fix For: 1.6.0 > > Attachments: OAK-5446.diff, OAK-5446-jr.diff, [#OAK-5446] > leaseUpdateThread might be blocked by leaseUpdateCheck.html, > OAK-5446.testcase, OAK-5446.testcase.v3, OAK-5446.xml > > > {color:red} > cloned from OAK-5446 due to internal JIRA issues > {color} > Fighting with cluster nodes losing their lease and shutting down oak-core in > a cloud environment. For reasons unknown at this point in time, the whole > process seems to skip about two minutes of real time. > This is a situation from which oak currently does not recover. Code analysis > shows that {{ClusterNodeInfo}} is handed the > {{LeaseCheckDocumentStoreWrapper}} instance to use as store. This is fatal > since any action the {{renewLease()}} tries to do will first invoke the > {{performLeaseCheck()}}. The lease check will, when the {{FailureMargin}} is > reached, _stall the renewLease() thread_ for 5 retry attempts and then > declare the lease to be lost. > The {{ClusterNodeInfo}} should instead be using the "real" {{DocumentStore}}, > not the wrapped one, IMO. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
