I have a droplet with 1GB of memory on which I only run an email server.
every couple of days I have to restart the server because I can’t ssh into it:
"ssh_exchange_identification: read: Connection reset by peer"
when I use the web-based console to login, and after I am dropped into the shell, I am unable to run any command:
$ ls zsh: fork failed: cannot allocate memory
since I am not running any other services (such as DBs) I believe 1GB of RAM should be plenty to run an email server, so I was wondering if this issue is caused by something else.
