I am using heavy forwarder at remote sites to forward data to a central indexer.
To make sure data is received we are using the useACK=true attribute.
On one of our sites, the connection is broken between the central indexer, so no forwarding can be completed.
Now the heavy forwarder, which is used locally as a search head is getting handshake timeouts, and prevents all GUI communication.
I would assume it is from failing to communicate to the central indexer.
We have tried to comment out heavy forwarder's outputs.conf file thinking that after a restart it would then be able to communicate....No such luck.
So....When a backlog of events to forward to an indexer builds up in a heavy forwarder, is there some file/directory we can delete to remove the backlog, and restore normal GUI communication?
