AFM High Active connections after upgrade to v11.6.1 HF2

Hi Experts , Recently we upgraded AFM guest units to v11.6.1.HF2 version. Host Units v12.1.0.(not upgrade)

 

Now our current active connections are very high .Any idea what is the cause for this ?any bugs in 11.6.1 HF2. Our Tcp profiles are fast L4 and pva setting is "pva-offload-state establish " .

 

Please advice!.

 

Thank you!
