connections without transactions continue to enter F5 and create a full session in the pool


hi everyone

I have a question from a customer where the end device (pool member) is experiencing a full session because there are many empty connections without transactions entering the pool member so that the device experiences a full session and it is analyzed that the source IP to the pool is self IP F5 which is F5. using the FastL4 protocol, is there a way or configuration so that F5 can reset or disconnect the empty connection or is there another more effective way to solve my problem?

Thank You


Hi @Margvin , 

Check your tcp profile which assigned to your virtual server ( in the client and server sides ) and check idle timeout intervals , you should set a suitable time ranges the default should be 300 sec == 5 mins for the connection to be idle. 

Please review this article too :

Also this an important article for idle sessions definations : 
it's important to keep all objects and profiles with suitable idle timeout like ( TCP profiles , SNAT ) which I think you're using in your current deployment.
