With the latest 13.1 63.18, VPX and MPX, it seems the packet engine crashed after a change of connectivity on data link, I also had the VPX used for GW that rebooted, crash. Anyone having a similar issue?

The same issues for 14.1 72.61 - Packet Engine Crash… raise support ticket with Citrix Support

Thanks Arthur, will raise one shortly

By the way - are you using AppFlow ?

Yes I do, it wouldn't be the first time that AppFlow is responsible for the crash.

You are absolutely right. Disable AppFlow and test it. The small number of crashes might indicate that, once again, the root cause of the issue is an incompatibility between the packet engine changes and AppFlow. Historically, Citrix does a very poor job of testing AppFlow before releasing new builds.

Thanks. I'll raise a case and see what they recommend, for now it seems to be only triggered when there is a change on the interfaces, not too bad.

Same issue here on 13.1 63.18 VPX with a GW and AppFlow. Opened a case last week for it.

Probably the same code issue for 13.1 line… Confirmed by Citrix a code issue in the 14.1-72.x line. It triggers only when all three conditions are met: • Adaptive Transport (EDT) enabled on the Gateway to backend path • Network Telemetry enabled on DDCs/VDAs • Appliance running the affected build Workarounds until the fixed build ships: Option 1: Disable Network Telemetry via Citrix policy on the Delivery Controllers/VDAs. EDT keeps working. Takes effect after session reconnect. Option 2: Disable DTLS on the VPN vserver: set vpn vserver name -dtls DISABLED Users fall back to TCP based ICA. Permanent fix is in development. If you see this pattern, check the three conditions before rolling back.

Thanks. EDT/DTLS is already disabled for me.

EDT/DTLS is already disabled for me too
