ICMP request failing

I'm running 11.6.1 on a vCMP guest with a IP forwarding server 0.0.0.0/0 as source and destination. Servers behind the LB (10.50.40.x) I cannot ping. I can ping all the way up to the transit VLAN on the F5 but none of the servers behind it. I see outputs like this in my capture:

    Do you have a the following configuration on the IP forwarding virtual server?

     

    Service Port = 0 (All Ports)

     

    Protocol = * All Protocols

     

    Protocol Profile (Client) = fastL4

    I failed over to the secondary and it started to work, which leads me to believe that after disabling arp and imp-echo, the primary hung or had a bad process. I enabled imp-echo and disabled arp, rebooted the primary, failed it back to active and it worked consistently.
