TCP Handshake Bug

I have a question, has anyone found the knowledge base (kb) for the TCP Handshake bug on the LTM (Hey guys this is the actual code name of the F5 bug but we are still looking for the KB for this one (597089-3)?

 

This bug appears to have the behavior of overriding the Idle timeout value with the TCP Handshake Timeout value and currently the fix is to disable the PVA Acceleration (FastL4 for us) of that virtual instance.

 

Any assistance for this would be greatly appreciated.

 

Thanks in advance

    Thanks CRodriguez. This is what we are currently doing but I was wondering if there was perhaps a code upgrade to fix this permanently so that we wouldn't have to disable the PVA (FastL4) across our enterprise. Plus we only know about the issue when our customers complain about certain behaviors that would lead us to verify if they are going thru one of our many F5 appliances and then if they are and the timeout has been overwritten by the TCP Handshake value then we would disable/uncheck the FastL4 for that instance.

     

    Thank you
