Universal Forwarder stop Forwarding

[jeanfrederic]

Im using Splunk Cloud,

and every once in a while, im getting this error

05-13-2015 09:10:34.891 -0400 WARN TcpOutputProc - Forwarding to indexer group splunkcloud blocked for 207000 seconds.

After that, my indexer is not indexing anymore.
Inside the log, I continue to see thing like this :

05-13-2015 09:07:16.757 -0400 WARN TcpOutputProc - Possible duplication of events with channel=source::WMI:AllReplicatedFolder|host::server1|WMI:AllReplicatedFolder|53003616, streamId=12722903640634641263, offset=516887 subOffset=1 on host=54.174.234.168:9997
05-13-2015 09:07:16.757 -0400 WARN TcpOutputProc - Possible duplication of events with channel=source::WMI:AllReplicatedFolder|host::server1|WMI:AllReplicatedFolder|53003616, streamId=12722903640634641263, offset=298120 subOffset=1 on host=54.174.234.168:9997

So I guess the forwarder continue to gather informations from differents servers.

I have to restart the service to make the cloud index again.

This universal forwarder is making WMI request to 30 differents server and push information to the cloud.
I have the exact same wmi.conf file on a "local test machine" wich is splunk enterprise 6.2.2 and it never stoped to index the same information.

Any one have the solution ? Thanks

For some reason, It turned to be my Universal Forwarder that was sending "duplicate" by itself.

My Splunk Enterprise Index was all right, around 2200 entries... and My Splunk Cloud was having 1 200 000 entries.
They both use the same wmi.conf

I dont know why I was having those duplicate.

How did you set your forwarder? Using a Deployment Manager?

Also what O/S is it running on? I've seen some similar behaviour on Windows forwarders in the past.
