Hi,

 

 

There is a limit with TCP of 2^16 = 65535 theoretical connections between two hosts. Other than that I don't think LTM enforces any limit on the number of TCP connections one client can open to a VIP.

 

 

What is the issue you're seeing? Have you been able to capture tcpdumps of the failure? Is there anything interesting logged to /var/log/ltm on LTM?
