I have some of the messages being truncated in Splunk though all other similar messages are parsing perfectly. There is no error of Truncation in the logs. Messages are of 400 lines/event.
TRUNCATE = 0
MAX_EVENTS = 1000

(Thu Apr 2 14:48:56 2020) to be accepted. If this is a correct time, MAX_DIFF_SECS_AGO (3600) or MAX_DIFF_SECS_HENCE (604800) may be overly restrictive.

If this timestamp is correct, consider adjusting MAX_DAYS_AGO and MAX_DAYS_HENCE. Context: source::/APPLICATIONS/WebSphere/Logs/rxxx/xxxxEndpointCLONE2/
