Thanks to some comments and some linux commands (like dmesg) I found maybe a solution for the qube. I came across the problem about:
Unable to load interpreter /lib/ld-linux.so.2
I changed the file-max (which was 4096) to 32768
echo 32768 > /proc/sys/fs/file-max
so let’s see if this helps. (I think not, cause I still see the error. So I think my Qube needs more memory)
About /proc/sys/fs/file-max:
Using “echo” to change the setting isn’t permanent… you need to put it in /etc/sysctl.conf (assuming you have that file) in a format like this:
fs/file-max = 32768
You can tell if the box is short of ram by running “vmstat 1”. Two columns should be displayed under “swap”, “si” and “so”. If you are seeing many non-zero figures in these columns, it’s likely you are running into ram problems. This will slow things down, which would mean more filedescriptors are open at once (since it can’t deal with things fast enough to close the filedescriptors), which means you are more likely to hit the filedescriptor limit..
