So ran into something fun with the 13.0-84.11 firmware for the ADC. After moving to this version, we noticed the packet engine crashed and failed over. Then it did it again a few days later. After a call with Citrix, looks like there is a known bug in there that is to be remediated in the next month with a new firmware release. The recommendation to do the fix is to run this command on each node of an HA pair: nsapimgr -ys enable_ica_edtinsight=0. There was a CTX article that was referenced (https://support.citrix.com/article/CTX341028), but I was unable to view it. There is a caveat if you happen to be using EDT that it won’t show in ADM after you make this change, so you would need to disable HDX Adaptive Transport if you want to see session information in ADM.
