Knowledge bundle Error : directory contains large lookup file

[Master_Blaster]

Hi All, 
I have an Warning message on my search head GUI as below:

"The current bundle directory contains a large lookup file that might cause bundle replication fail. The path to the directory is /opt/splunk/var/run/hostename-randomnumber-randomnumber.delta"

When i validated respective delta file, it's not even one MB. Still getting this Warning message frequently. Could anyone please help ? i see same messages on splunkd.log too.

-rw------- 1 root root 188M Apr 2 10:36 hostname-1617352591.bundle
-rw------- 1 root root 80K Apr 2 10:36 hostname-1617352525-1617352591.delta

That warning is triggered by a lookup file that is larger than 50MB.  If this is not a concern for you then consider changing the value of  conf_replication_summary.concerning_file_size in server.conf.

How to get the lookup file name causing issue?

Examine the bundle file.  tar -tf <bundle-file-name>
