GlobalProtect v5.2.4 client disconnects with "Received a virtual interface packet with fragment"

I am running GlobalProtect client 5.2.4-21, experiencing frequent disconnect events accompanied in PanGPS.log by the following:

 

(T10852)Debug(1564): 01/11/21 17:33:00:578 Received a virtual interface packet with fragment 0x2000
(T10852)Debug(1564): 01/11/21 17:33:00:578 Received a virtual interface packet with fragment 0xAC
(T10852)Debug(1564): 01/11/21 17:33:01:779 Received a virtual interface packet with fragment 0x2000
(T10852)Debug(1564): 01/11/21 17:33:01:779 Received a virtual interface packet with fragment 0xAC
(T10852)Debug(1564): 01/11/21 17:33:01:894 Received a virtual interface packet with fragment 0x2000

...

 

These lines keep repeating until the connection restores itself. During the disconnection event, the GlobalProtect client remains "connected" to the network, it's just that no traffic seems to make it back -- all connectivity appears to be lost from the user's perspective. It usually takes 30-90 seconds for the normal connectivity to resume. These events typically happen 2-3 times an hour during the work day. 

 

Does anyone have an idea what might be causing this?

We are experiencing the error message with 5.2.4.   We are going to try the latest 5.2.5 to see if this resolves, else, we are going to downgrade to a 5.1.x version.  Recommend you do the same, do some testing, and let us all know.

 

You can also try to Collect Logs and open a ticket with TAC.

 

Changes were made in 5.2.x to allow IP fragmentation, but I think this is breaking something.
