The script was killed

Hi,
I have problem with my VPSs. When I click on run.sh, the script runs few minutes. After that there is message "killed" and script stops. Could you help me?

hi,

Log messages like "SQL statement required..." are harmless.

What OS is this and how much free memory the process can use?

Maybe try to call run.sh with parameter --daemon
