We have recently upgraded the Splunk SearchHead and Indexer to Splunk V6. Since afternoon we are facing below error and no logs are coming on Indexer or Search head. 1. Search peer lonrs10215 has the following message: Tcp output pipeline blocked. Attempt '400' to insert data failed.
I looked at the splunkd.log on indexer and can see below error message:( 11.192.36.204 is the Indexer server lonrs10215 mentioned in above error)
01-07-2014 18:10:33.233 +0000 WARN TcpOutputFd - Connect to 11.192.36.204:9997 failed.

When i tried the command (netstat -an | grep 9997) on indexer I can see its connecting and have established connections: tcp 24778 0 11.192.36.204:9997 11.182.8.168:2621 ESTABLISHED tcp 1304190 0 11.192.36.204:9997 11.182.8.168:2620 ESTABLISHED tcp 1613142 0 11.192.36.204:9997 11.192.36.204:46875 ESTABLISHED
Can you please suggest to resolve this?
Thanks Nik
