think I found the problem, top shows:

MiB Mem :   3906.0 total,     71.6 free,    375.9 used,   3458.6 buff/cache
MiB Swap:    100.0 total,     19.9 free,     80.1 used.   3364.1 avail Mem


kernel claims all memory space as cache,  that leaves virtually nothing (here
only 71.6 MB) for programs
those programs then start swapping!


BAD BAD BAD
Linux error!!!!

Big thread about it here with possible solutions:

I have an old PC running this software with old Slackware kernel with maybe 1G
of memory for 6 month 24/7 no problem..
That is where the old setup came from.
But it had a much bigger swap partition, maybe never noticed this.

What is the point of using all memory for caching?
Makes no sense to me.
Is Linux DEAD?
