Eventgen: Unable to generate multiple output files with defined size

[conaku]

I want to generate multiple output files with defined size using the "fileMaxBytes" and "fileBackupFiles" parameters but these parameters are not working for me. Please suggest.
Here is the configuration file that I have developed:

[global]
generatorWorkers = 10
threading = process
#threading = thread

mode=sample
sampleDir = /root/ashish/cybersecurity/splunk_eventgen/eventgen/lanl_datagen
