So does this seem like a normal process list for you guys? I am getting a LOT of crashes since upgrading my VPS from a single core of an Intel Xeon 2014 to a dual core Xeon 2019, with double the RAM. I suspect I did SOMETHING wrong when I moved the files, databases, etc.
I see php-cgi7.2 and that might cause crashes which could be avoided with php-fpm. I also see spamd child and freshclam. You are asking much from a 1 GB system and it is difficult to imagine you had these two on your old 512 MB system, so double check that.
