[6.11+] "nchan/device list" process maxing a cpu core for 5 seconds every 30 seconds

6.10.3 and earlier work fine. 6.11+ including 6.12 maxes a CPU core for about 5 seconds every 30 seconds. This process shown in HTOP accumulates about 3 seconds of CPU time after each spike:

 

/usr/bin/php -q /usr/local/emhttp/webGui/nchan/device list

 

Any idea what might have changed here 6.11+? This recurring spike happens even in safe mode with the array stopped. I'm not positive it's this process causing my problem, but its behavior seems suspect.

 

It's making newer releases of unraid unusable for me, because the spike seems to eventually land on a CPU core assigned to a VM, making the VM unresponsive while the spike is happening.

 

Safe mode 6.12.0 diagnostics attached.

 

System:

ASRockRack E3C246D4U Motherboard
Intel® Xeon® E-2288G CPU @ 3.70GHz
Dell PERC H310 8-Port 6Gb/s SAS Adapter RAID Controller
