What does Splunk log "rollout" refer to?

[nagarjuna280]

I heard the word "rollout" regarding /opt/splunk/var/log/splunk files

[somesoni2]

The rotation of Splunk internal logs files, available in $SPLUNK_HOME/var/log/splunk folder, is managed by log.cfg file. The by default they roll to a new file when the log file size reaches 25MB (specified in bytes) and 5 backup/rolledover files are retained. See below links for more details:
