Failed to flush outgoing items


Trying to upgrade from 1.1.12 to 1.2. ES version is 0.90.2.

Current setup works fine as is but when I tried to upgrade, some logs get through to ES and the majority don't. The error in LS log is -

At the same time, the error in Elasticsearch log is -

Note that this setup works fine in Logstash 1.1.12 and I am unsure how to narrow down which config/logs are causing this from the 110 shippers I have.

I just tried 1.3.1 and I'm getting "Failed to flush outgoing items" errors processing Cisco ASA syslogs. So how is this fixed?

"Fixed in next release"

Is this fixed then?

@Jason, I don't experience this issue anymore, so, at least for me, I would say it is fixed. For the record, I'm using Logstash 1.3.3 and Elasticsearch 0.90.12.
