> Key: NIFI-10702
> URL: https://issues.apache.org/jira/browse/NIFI-10702
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core UI
> Affects Versions: 1.18.0
> Environment: RedHat 6 using openjdk 11 2018-09-25
> OpenJDK Runtime Environment 18.9 (build 11+28)
> OpenJDK 64-Bit Server VM 18.9 (build 11+28, mixed mode)
> Reporter: Aaron Schultz
> Assignee: Kulik Gábor
> Priority: Minor
> Time Spent: 10m
> Remaining Estimate: 0h
>
> After almost exactly 1 week of running 1.18.0, previously configured GetSMBFile processes are reporting that they cannot retrieve files due to "Different server found for same hostname" error. This happened on more than 1 of my GetSMBFile connectors. There does not appear to be a way to force it to "forget" the server; restarting the processor did not fix it. A full NiFi restart does resolve the issue.
