After upgrading to BIG-IP 17.1.0, observed that some of the client sessions are orphaned, this has caused multiple intermittent connection failures when connecting through BIG-IP. When the FastL4 profile with loose-* settings enabled is used and an idle timeout of 300 seconds, after idle time of 300 seconds, the server-side connection resets but no reset is sent towards client.
Some client sessions will be orphaned and cause intermittent connection failures when trying to connect through BIG-IP.
- Use BIG-IP version 17.1.0 and above - Use Fastl4 profile with loose-* settings enabled. - Configure idle timeout values.
If not required for a particular use case, then disable loose-close settings in Fastl4 profile.
