WLED rebooting every 15-30m until I cleared the mDNS field (disabling it) #5336
Description
What happened?
My two WLED lamps have started rebooting on their own every 15-30 minutes. Swapping the power supplies and adding a capacitor didn't make a difference.
To Reproduce Bug
- Firmware: v0.15.3
- Build 2508020
- Free heap: 179.4 kB
- CPU clock: 240 MHz
- Flash size: 4 MB
- Filesystem: 40/983 kB (4%)
- Environment: esp32 v3.3.6-16-gcc5440f6a2 (0)
- Hardware: ESP32-WROOM-32D
- Wifi environment: Ubiquiti Pro AP 6E
- Used with HA + WLED integration
Detail: My two WLED lamps have recently started rebooting every 15-30m. After some searching, I found people claiming that clearing the mDNS field in Config -> Wifi cure the rebooting. I tested and this seemed to be the fix.
The correlation seems to be that I recently setup a Matter server and Thread Border Router to use with HA and paired about 9 devices to it. I assume Matter/Thread is mDNS heavy and this seems to crash WLED or causes these reboots.
During the process of elimination, I installed the most recent 0.14.x firmware onto the ESP32 but it was still rebooting all the same, so I updated them both back to 0.15.3. Next, I cleared the mDNS field from one of the WLED lamps and so far it's been up for 1h 30m and counting. The other one is still rebooting every 15-30 minutes. This appears to be the fix.
Expected Behavior
WLED shouldn't reboot on its own.
Install Method
Binary from WLED.me
What version of WLED?
WLED 0.15.3 Build 2508020
Which microcontroller/board are you seeing the problem on?
ESP32-WROOM-32D
Relevant log/trace output
Anything else?
The fix (for now) is to just disable mDNS.
