On v1.5.3 and v1.5.4 I noticed sometimes the SDR freezes, It just shows a black waterfall and S9+60 S-Meter:

You have to restart the Service then again to get it working
Atm visible at Zug SDR

PS: It happen mostly on the RX888:
Log in console shows endless:
Dropping Audio due to buffering slow client
and
[2024-09-08 21:53:01] [error] handle_read_frame error: websocketpp.transport:7 (End of File)
What toml settings do you use?
Did you update /etc/default/grub ?
GRUB_CMDLINE_LINUX_DEFAULT="systemd.unit=multi-user.target usbcore.usbfs_memory_mb=512 pci=noaer"
The systemd.unit parameter prevent the GUI from starting...can be started with startx or remove the param if you want the GUI.
Did you add to /etc/sysctl.conf
kernel.perf_cpu_time_max_percent=0
Did you install cpufrequtils and lock the CPU to performance and e.g. 2G min/max cpu speed?
Never set max speed, as the CPU may get too warm and/or crash.
Just some ideas to try.

Can you post the TOML file you use?

In the attachment, I have a output of dmesg on this system, maybe someone sees any impotrant stuff inside it
https://devopsx.com/intel-gpu-hang/#increase-driver-timeout maybe ?
be careful and check values before change
Couple of things I have noticed.
The GPU i915 hang is a known Linux problem, if I'm not mistaken it uses a wrong driver, you have to Google for it, as many more people have i915 problems.
https://askubuntu.com/questions/1306700/fixing-gpu-hang-caused-by-i915-driver
Second, change this in your config:
threads=3 <= you have 1, meaning the webserver can run out of CPU-cycles.
fft_size=8388608 <= I noticed it needs to be much higher.
fft_threads=1 <= the waterfall doesn't need more when the GPU is used, it brings nothing.
Also check with intel_gpu-top that your GPU doesn't run out of memory, maybe use a bigger GPU memory in the BIOS, mine is set to maximum of 512MB, just to be sure.
