Hello, I am using the x86 device miniforum gk41, OpenWrt 18.06.8 kernel is 4.14.25,1000Mbps LAN，When traffic is too large kernel panic.
cool!
would be even cooler if we knew what unit and version Openwrt it was 
Hello, I am using the x86 device miniforum gk41, kernel is 4.14.25
and what openwrt image did you use ?
I'm using OpenWrt 18.06.8, 1000Mbps LAN，When traffic is too large kernel panic.
And you couldn't fit all that info into your 1st post ?
start by upgrading to 19.07.4.
Okay, thank you very much！When I cannot upgrade to openwrt 19, my program running on openwrt 18.
OK,
What network chips does your mini computer have ?
Does it crash under load even if you don't use your program ?
Could also be a heat issue.

I think it has nothing to do with heat dissipation. The kernel panic will only occur when the traffic is large. My device configuration is,
CPU Intel® Celeron® Processor J4125, 4 Cores/4 Threads(4M Cache, up to 2.70 GHz)
GPU Intel® UHD Graphics 600
Memory LPDDR4 8GB (On Board)
Storag M.2 2280 128GB SATA SSD
Wireless Connectivity IEEE 802.11ac Dual-Band Wi-Fi, BT4.2
Ethernet 1000Mbps LAN realtek rt640
More traffic = more heat, from CPU and NICs.
I assume your device is used as a router ...
