Switch to PHP 7 (out of memory)

Hello everyone, I wanted to try PHP 7. But are digitalocean and I only have 1gb of ram.

Usually my server runs on these numbers.



Trying to move to php7 at some point the process hangs because out of memory. The server still works, but lost some configuration back to php5.

I thought to do Drop cache memory, but I do not a clear idea what to do. [DC] could create problems to the server and to my sites?

I just started to move my sites cwp, so do not risk immense damage, but I do not even want to start all over again ...

My sites are quite up to date, all PDO and html5. There may be other problems in the transition to php7?

If just does not work, I can go back to php5? I lose everything?

restart server and try again add some swap to your server

Just reboot immediately goes to 9 Gb.

What do you mean by

add some swap to your server

Hi, if you have a problem with RAM, ask your hosting provider to add SWAP file.
