[Bas ON5HB]

Is your websdr running out of samples to process?

Or it the CPU too weak to run that many threads?

What CPU are you using?

What does 'dmesg' tell you when it happens?

Has the RX888 been modified thermally? If not the USB-chip gets too hot and start giving errors, but worse in a few days it will die.

All the rest looks fine to me.

[hb3xdc]

CPU (Intel(R) Core(TM) i5-6600T CPU @ 2.70GHz), RAM and Thermal of RX888 should be fine. Maybe something in here, some usb powersave or so.

Seems your Kernel doesn't like it...perf errors, where it tells you it hoggs the system....

Try adding this to /etc/sysctl.conf

Code Select Expand

kernel.perf_cpu_time_max_percent=0
Just add it at the end and reboot.

It's a protection mechanism....see if it helps.

Get also this error sometimes. Seems not related to usb as I use only gigabit ethernet input.
Will run in gdb soon to track the bug.

[magicint1337]

Ill also look at it soon again but gdb didnt really help me.

Did you apply the Chat-box crash fix? See top post in this section of the forum.

[Phil - NY4Q]

Maybe I am fortunate, but I have not had any crashes that were the fault of the PhantomSDR+ application. The one crash I have had was when I was moving the PhantomSDR+ apps to use systemctl and did not kill all processes that were already running. That was my fault. And I also have not made the chat-box mod because I was not having crashes. So with that I thought I'd post how I built my system and maybe there is something in there that is different.

My CPU = Xeon E5-1620 v3 @ 3.50GHz
My GPU = NVIDIA Corporation GP106 [GeForce GTX 1060 3GB]
System RAM = 16G
Storage is a 250G SSD

I begin with installing Ubuntu 22.04.5 Server.

I apply all the updates and go no further than Ubuntu Server 22.

I install the NVIDIA drivers for my GPU and remove any Ubuntu drivers for that card that was installed during the
initial install.

I verify OpenCL is working for my GPU.

After these steps are accomplished, then I run the auto install on Steven's github and correct any errors that I see on the compile. Check that screen closely and look over any dependencies that may fail and fix those before moving on and something else I do is rm -rf the PhantomSDR-Plus directory path before starting another compile.

I fix the dependencies, then try a fresh run.

So far, so good. I have had no crashes and I am seeing sometimes near 80 users on the weekends.

[F5OEO]

Running gdb for hours, and no crash at all. It will not help tracking the bug !
