Why error "Unable to import data.File too small to check seekcrc, probably truncated. Will re-read entire file"?

[power12]

I am trying to import data reading a file .But I keep getting the below error in internal logs

INFO WatchedFile - File too small to check seekcrc, probably truncated. Will re-read entire file='/usr/local/ios/var/logs/PN_Usage_iujj_Jun28.22.10.56.csv'

inputs

#crcSalt = vmr
initCrcLength = 10000

Is there any other settings I need to include or remove.

Thanks in Advance

Hi there,

Your inputs.conf setting of `initCrcLength = 10000` tells Splunk to read 10000 bytes into the file to validate the seekcrc or if this file was seen before. If your file is smaller than 10000 bytes Splunk will report the message you see and re-index the file. This behaviour is expected as described in the docs https://docs.splunk.com/Documentation/Splunk/9.0.0/Admin/Inputsconf#MONITOR:

Try to remove the option `initCrcLength` and restart Splunk.

Hope this helps ...

cheers, MuS
