search app error : skipped indexing of internal audit event will keep dropping

[duongl2]

skipped indexing of internal audit event will keep dropping events until indexer congestion is remedied. Check disk space and other issues that may cause indexer to block

I clean event data (splunk clean eventdata & restart splunk. it still the same issue.
what is going on? thanks
file system is fine: f
ilesystem Size Used Avail Use% Mounted on
/dev/sda1 12G 3.8G 7.6G 34% /

So We have been receiving the same error message...
Please tell us how many splunk server do you have and if you have some working as heavy forwarder. Please.
Have you already checked the status of network connections or the throughput of it... ?!

the redhat yum update is running on the background. after stop that service; it is fine.
