Initially the log was indexed correctly, line by line. However, i recently noticed splunk takes in multiple lines as one event. It also no longer recognised the timestamp defined for the log file (through field extraction). It seems to take in the file creation date/time as the timestamp instead. All the related reports are affected.
The problem was observed even when splunk runs in stand-alone mode. And i tried some of the methods mentioned in the forum, but they did not help.
