Opened: Jan 31, 2014 Severity: 4-Minor
fastl4 tcp-handshanke-timeout value does not change to become the idle timeout value after TCP 3 way handshake completes.
Instead of switching to the idle timeout value after the 3-way handshake completes, a connection can retain the tch-handshake-timeout value, which could cause it to timeout early.
This issue is transient and occurs when using a fastl4 profile. After the system returns to the TCP_CLOSED state, it will be OK.
None
