Microsoft Azure Service Fabric 6.5 Fifth Refresh Release Notes

Service Fabric Runtime

Versions IssueType Description Resolution
Windows 6.5.676.9590
Ubuntu 6.5.476.1		 Bug Memory leak when calling the FabricClient.QueryManager.GetDeployedReplicaListAsync API Impact: Memory leak occurs whenever the FabricClient.QueryManager.GetDeployedReplicaListAsync API is called.
Fix: Identified the leaking code and fixed it to free the memory when no longer in use.
Workaround: None
Windows 6.5.676.9590
Ubuntu 6.5.476.1		 Bug The list of deactivation tasks returned in node query result has some extra invalid entries Impact: Usability issue. The user sees some invalid entries in the node query result. e.g. the result returned by the Get-ServiceFabricNode PowerShell cmdlet.
Fix: Fixed the code to not insert those invalid entries into the node query result.
Workaround: Ignore the invalid entries. The deactivation task type for those invalid entries would be "Invalid". Such entries could be ignored.
Windows 6.5.676.9590
Ubuntu 6.5.476.1		 Bug The default timeout (10 minutes) for WaitForReconfiguration and WaitForInBuildReplica safety checks during upgrades and node deactivations is too short. Impact: In some scenarios, the failure of WaitForReconfiguration and WaitForInBuildReplica safety checks implies that the upgrade or node deactivation would cause availability loss if it were allowed to proceed. The timeout for these two safety checks is 10 minutes by default. After the timeout period elapses, Service Fabric allows the upgrade or node deactivation to proceed even if the safety checks are failing. In some scenarios, this can lead to availability loss for the partition that is failing the safety check.
Fix: The default timeout for the WaitForReconfiguration and WaitForInBuildReplica safety checks has been made infinite to avoid availability loss situations.
Workaround: Change the default timeout to a very high value using the WaitForReconfigurationSafetyCheckTimeout and WaitForInBuildReplicaSafetyCheckTimeout parameters in the FailoverManager section of cluster settings. https://docs.microsoft.com/en-us/azure/service-fabric/service-fabric-cluster-fabric-settings#failovermanager
Windows 6.5.676.9590
Ubuntu 6.5.476.1		 Bug Provisioning an application strips native DLL files off user application package, when they are common with Service Fabric runtime. Impact: Application can have an error in runtime by wrong version of binaries.
Fix: gRPC binaries are added to whitelist that doesn't filter out from user application package.
Workaround: None
Windows 6.5.676.9590 Feature Enable the user to keep the DNS suffix empty Brief desc: Previously Service Fabric would append the service name as a suffix to a DNS name by default. Previously there was no way to override this setting. Now the user can use a hosting setting so that no suffix will be appended.
How/When to Consume it: In fabric settings, set the Hosting parameter DefaultDnsSearchSuffixEmpty to true.
Windows 6.5.676.9590 Bug Upgrade failure 6.4->6.5 rollback caused DNS to no longer resolve remote queries Brief desc: There is a corner case where if 6.5 doesn't clean-up DNS correctly 6.4 will open DNS and cause a corruption of the DNS server list such that it only has the SF DNS IP address (localhost IP) and can no longer resolve remote queries.
Impact: This will cause DNS resolution to completely fail for remote query.
Workaround: Manually correct the DNS server list to include a remote DNS server such as Azure DNS.

Service Fabric Common Bug Fixes

Versions IssueType Description Resolution
Windows 6.5.676.9590 Bug Improve DNS intermittent resolve errors Brief desc: Intermittent resolve shows up as short periods of time where a resolve will timeout or be unable to correctly statisfy a request.
Impact: Causes interruptions in service for customers.
Workaround: Wait for it to self correct or apply a patch script.
How/When to Consume it: In fabric settings, set the Hosting parameter DnsServerListTwoIps to true. **Documentation: https://docs.microsoft.com/en-us/azure/service-fabric/service-fabric-cluster-fabric-settings#dnsservice
