Description

My pfSense box is running out of memory while it should have plenty to do what it does.

2.4.3-DEVELOPMENT (amd64)
built on Sat Dec 30 11:07:37 CST 2017

Running on a Virtualbox with 1GB memory and 1GB swap space.
Dashboard and htop shows both memory and swap being 'full'.

Also on console these messages pop up:
pid 77785 (php-fpm), uid 0, was killed: out of swap space
pid 1083 (php-fpm), uid 0, was killed: out of swap space
pid 53694 (php-fpm), uid 0, was killed: out of swap space
pid 65729 (php-fpm), uid 0, was killed: out of swap space
pid 48018 (php-fpm), uid 0, was killed: out of swap space
swap_pager: out of swap space
swap_pager_getswapspace(16): failed
pid 1082 (php-fpm), uid 0, was killed: out of swap space
swap_pager_getswapspace(7): failed
swap_pager_getswapspace(4): failed

After running on console '16 restart php-fpm' memory usage drops to 272MB memory and 216MB swap used. So about 1.5GB of memory was released..

I believe this is might be related to https://github.com/pfsense/pfsense/pull/3881

Output of some commands attached:
curl -k "https://localhost/status?full" > mem_phpfpm_status_full.log
