Packets between TMM and a pool member are dropped
The client hangs and traffic is disrupted due to not being able to complete the client's request
- BIG-IP Virtual Edition - Single NIC - Virtual Server with at least one pool member - Virtual Server connects to a pool member using ports 22 or 8443. This can occur randomly if using ephemeral ports or guaranteed to occur if user configured these ports be used when making connections with something like 'preserve source-port'
Do not use ports 22 or 8443 for handling client traffic and specify some other port instead Alternatively, if these ports must be used to handle traffic, change the httpd management port to a port which will not be used to handle traffic.
