a proxy_module question ,maybe a bug?

[村长]

nginx version: nginx/1.10.3
uname: Linux  4.9.0-8-amd64 #1 SMP Debian 4.9.144-3.1 (2019-02-19) x86_64 
GNU/Linux
VPS: Linode $5



I set about 900 subsite like this:


    proxy_cache_path /var/cache/nginx/abc.com/aaa levels=1:2 use_temp_path=off 
keys_zone=aaa.abc.com:64k inactive=8h max_size=128m;
    proxy_cache_path /var/cache/nginx/abc.com/bbb levels=1:2 use_temp_path=off 
keys_zone=bbb.abc.com:64k inactive=8h max_size=128m;
    ...
    the list is 900+



    server {
        listen       80;
        server_name  ~^([^.]+)\.abc\.com$;
        set $sub $1;
        location / {
            proxy_pass   https://172.22.207.56/;
            proxy_redirect https://172.22.207.56/ /;
            proxy_set_header Host $sub.abc.com;
            proxy_cache $sub.abc.com;
        }
    }



the nginx.conf is:
user www-data;
worker_processes auto;
pid /run/nginx.pid;
include /etc/nginx/modules-enabled/*.conf;



events {
    worker_connections 4096;
    multi_accept on;
    use epoll;
    worker_aio_requests 256;
}

http {

    proxy_set_header Accept-Encoding "";

    proxy_hide_header Set-Cookie;
    proxy_hide_header Expires;
    proxy_hide_header X-Accel-Expires;

    include /etc/nginx/sites-enabled/*;

}

I used wget to download every subsite's index page, in order to active the 
cache，per 6 hour , crontab。 just like this:


*    */6    *    *    *    /usr/bin/wget -t 1 -qi 
/root/.script/linklist-80.wget -O /dev/null


when I mannually type the command first:


wget -t 1 -qi /root/.script/linklist-80.wget -O /dev/null


everything is good. about 130minutes.



but when I type run it again at once, the nginx will go wrong in minutes:

...


until entire disk full.


what's wrong with my config files ? or what's wrong with nginx?
