    Hello Team,

    We have raised F5 case for this issue and F5 Internal team have found few logs and few TCP half-open (SYN cookie) vector which might be causing this issue which are related to AFM module. To isolate the issue internal has suggested to upgrade the tenant to the latest 17.1.1.4 (stability release) and F5OS to at least 1.5.2. and After upgrading the tenant to version 17.1.1.4 and F5OS to version 1.5.2, the issue has been resolved.
