D80 flooding httpd log and high cpu usage

I have a client where they leave a D80 phone sitting on the parking list.

This floods the http access_log log with:
AA.BB.CC.DD - - [22/Dec/2025:12:20:52 -0500] “POST /dphoneApi.php/json HTTP/1.1” 401 28 “-” “Digium-D80/1_12_14/000FD30BXXXX”
AA.BB.CC.DD - 1013 [22/Dec/2025:12:20:53 -0500] “POST /dphoneApi.php/json HTTP/1.0” 200 450 “-” “Digium-D80/1_12_14/000FD30BXXXX”

This also causes the httpd service to take up considerable amount of CPU.

2 core VM that usually sits around 5-20% CPU now hovers around 50-90% CPU usage.

Outside of end user training what else can be done to reduce the CPU usage?

What’s also interesting is I took a P320 phone as well, opened up the Parked Calls menu and went ham on the refresh button. I was able to cause the CPU load to spike and stay at 100%

Anyone else seeing this behavior?

Getting hounded by customer on this. Is there something more I need to look into?
