In our Splunk enterprise event logs are not breaking.
Two events are coming as one event.
It happens when your log data is not able to parsed correctly by Splunk automatically (if you don't have to event breaking rules defined for the sourcetype you're using and your data format is not following default Splunk's rules) OR your log data format is different from the rules you've defined for your custom sourcetype. Check what sourcetype you're using, if you've event breaking defined for that sourcetype and if log data is following that event breaking rule.
