Products

• VMware Tanzu Gemfire

Issue/Introduction

Symptoms:

Starting with GemFire 8.1.0, when running a backup disk-store command in GFSH, the following warning message appears in the locator log:

[warning 2015/07/24 18:36:14.957 CST loc1 <RMI TCP Connection(3)-192.168.6.1> tid=0x69] Received reply from member DADI-PC(loc1:11228:locator)<v0>:37912 but was not expecting one. More than one reply may have been received. The reply that was not expected is: com.gemstone.gemfire.admin.internal.FlushToDiskResponse

[warning 2015/07/24 18:36:14.964 CST loc1 <RMI TCP Connection(3)-192.168.6.1> tid=0x69] Received reply from member DADI-PC(loc1:11228:locator)<v0>:37912 but was not expecting one. More than one reply may have been received. The reply that was not expected is: com.gemstone.gemfire.admin.internal.PrepareBackupResponse: [856aa721-6c87-48bd-af3e-1d51d361272b [DADI-PC:C:\lab\JAVA8test\loc1\ConfigDiskDir_loc1]]

Environment

Cause

This warning message can be safely ignored. When the locator is performing a local backup on its disk store, it passes the result into reply processor. The reply processor then logs the warning since it is only expecting to receive replies from other members and not the locator itself.

Resolution

The fix of this bug is currently planned to be included in new versions after GemFire 9.0.
