Quote from: Bas ON5HB on Jul 13, 2025, 06:59 PMThe curl from the github has 4.8.0 libs, not 4.7.0

So I removed 4.7.0 and replaced it with 4.8.0 from the github.

And I get the same message too, exactly the same.

Well I tried to point it to 4.8.0, but it gave the same message, so I moved it to 4.7.0 and it was ok then. SO, there is still some of the Ubuntu stuff on there or something. Maybe I need to do apt purge curl...?

I have had another crash as of an hour ago.

I also noticed this.
Jul 13 14:06:43 websdr start-websdr.sh[3478320]: build/spectrumserver: /usr/local/lib/libcurl.so.4: no version information available (required by build/spectrumserver)

I think this was caused by the removal of Ubuntu's curl and the install of the latest. I fixed this by deleting the old pointer to library and created a new pointer to the updated library.

sudo rm /usr/local/lib/libcurl.so.4

Then make a new symbolic link pointing to the new library.
sudo ln -s /usr/lib/x86_64-linux-gnu/libcurl.so.4.7.0 /usr/local/lib/libcurl.so.4

Then I recompiled spectrumserver and away we go.

And we crashed again with longjump...

Pfff....back 2 systemd files as only 1 doesn't restart the spectrum.

1 day and 14 hours....

And again....installed Curl 8.15-DEV and purged Ubuntu Curl, then recompiled spectrum, let's see what happens now.

Also changed compiling to -O1 for compiler options. Let's see what happens. Uses 2% more CPU now.

19 hours and no crash, fingers crossed

Fingers crossed....

After Bas' latest suggestions, I am at two days and 11 hours with no crashes.

I noticed that spectrumserver was slowly taking up more and more memory,
from 231 to 253 in two days and a few hours (i have 8Gb RAM on this computer).

And then, I change receiver band, only one user, crash. After 5 sec server works.
I edit spectrumserver.cpp, compile, and I back to one startup script (as Bas sugested).

Now server normal work.
Wait for next crash...

After Bas' latest suggestions, I am at 27 hours with no crashes.

I updated the buffers from 100 to 500, seems 100 is too low.

And in spectrumserver.cpp I changed the backlog size:

m_server.set_listen_backlog(16384); //Backlog upped from 8192 to 16384 for testing - Bas.
Maybe it's the backlog that is too small.

Test is running 4 hours now....so far no issues.

The only new condition is the heat - 38 and even 42 °C
To be honest, I am tired....

My receiver never (rarely) is the culprit. It is always spectrumserver. BUT, after Bas' latest suggestions, last check its at 23 hours with no systemd restart.
