    I may be running into this bug myself... I have an HTTPS monitor that is constantly marking the nodes as down/up again every 20 - 60 seconds. I am running a version that is affected by the bug. What logging settings do you need to have configured for Local Traffic Logging to see this error?

    I may be running into this bug myselfi think node should always be marked down if you are hitting that bug. by the way, have you ever tried troubleshooting steps Aaron wrote in the following article?

    i think node should always be marked down if you are hitting that bug. i thought the bug happened after it was marked up due the initial connection, after the node tried to initiate the renegotiation. the "ssl renegotiation is not allowed" message led me to believe it was on the f5, since the VIP had ssl renegotiation disabled to fix the tls vulnerability.

     

    by the way, have you ever tried troubleshooting steps Aaron wrote in the following article? Nope, I haven't seen that article yet. Curl looks like it could set me free, potentially. I'll give it a shot, thanks!
