Can anybody please tell me what I need to do for the error

ERROR TailingProcessor - Ran out of data while looking for end of header 

I tried reinstalling Splunk many times, but I don't know what to do for this error. Please advise, it's urgent.

It looks like this was a bug SPL-138909 "Ran out of data while looking for end of header- archive file" which has been fixed in the following releases:
6.5.6 +
6.6.4 +
7.0.2 +
7.1.0 +
7.2.0 +

While running Linux UF_6.3.7, I had this issue as well. Everything was correct in my config, but it was cured by reboot of host.

Is the file structured data? If not, you probably have INDEXED_EXTRACTIONS defined for this source, sourcetype, or globally; this will cause issues with the crc. While the issue manifests itself as TailingProcessor errors, btprobe behaves in the same way and is an easy test. You can replicate this with the license_usage.log, here with the setting sitting outside of any stanza (not recommended!):

> head -1 ./splunk/etc/system/local/props.conf
INDEXED_EXTRACTIONS = CSV

> ./splunk/bin/splunk cmd btprobe -d ./splunk/var/lib/splunk/fishbucket/splunk_private_db/ --file ./splunk/var/log/splunk/license_usage.log
Using logging configuration at ./splunk/etc/log-cmdline.cfg.
terminate called after throwing an instance of 'FileContentException'
  what():  Ran out of data while looking for end of header
Aborted (core dumped)

btprobe crashes!
We don't index license_usage.log!

If we rectify this, btprobe works, and we index the log:

Regarding the original problem:

My guess is that the csv file is formatted in such a way that Splunk does not recognize the line endings. I would edit the csv file with a text editor and make sure that it has appropriate line endings for the OS.

Then try to upload again.

This error indicates that Splunk is having trouble processing one of your inputs.
Does Splunk work properly otherwise? Does the message indicate which file is the problem?

Hi Iguinn,

Thanks for the reply. Yes you right it looks like Splunk is having trouble to processing the one of the input (.CSV). Other inputs went well. But I need to import the particular input.

Now I see below error,

The second error looks like a failed HTTP request, probably not related to the file input problem. If you have a lot of these, then that's a problem - but it is also a different question.
