When BIG-IP is configured with a PingAccess profile and an SSL profile is associated with both the BIG-IP virtual server and a ping access configuration, an active connection to the virtual server may lead to a TMM crash.


Traffic disrupted while tmm restarts.


-- SSL is configured on both the BIG-IP virtual server that contains the ping access profile and ping access configuration. -- Active connection to the BIG-IP virtual server -- Config sync is triggered or "tmsh load sys config" is triggered


No workaround.
