OLS 1.7.7 on my DirectAdmin / CloudLinux server seems to restart itself multiple times and creating core files. Any idea, please?

# /usr/local/lsws/bin/openlitespeed -v
LiteSpeed/1.7.7 Open
    module versions:
    modgzip 1.1
    cache 1.62
    modinspector 1.1
    uploadprogress 1.1
    mod_security 1.4
