[Pkg-nginx-maintainers] libnginx-mod-http-cache-purge seems to not work at all on 14.04 or 16.04

[Mike Klopot]

Hi,

It appears that somewhere between nginx versions 1.10.3 and 1.11.9 the
module provided by the libnginx-mod-http-cache-purge package has stopped
working completely.

The worker process gets killed with signal 11.

I can reliably reproduce this behavior:

syslog:

kernel: [28583513.474105] traps: nginx[27377] general protection
ip:7fdf652f3b67 sp:7ffcc89b1d58 error:0 in nginx[7fdf65281000+f6000]

___________________________

error.log debug info:

[alert] 7056#7056: worker process 27377 exited on signal 11

___________________________

Command:

curl -X PURGE -D - -o /dev/null http://127.0.0.1/

___________________________

Config:

proxy_cache_path /var/www/cache levels=1:2 keys_zone=mapserver_cache:8000m
max_size=400g;

server {

        listen 80 default_server;

        server_name $hostname;


        location / {

        proxy_cache mapserver_cache;

        proxy_pass http://spaz.org;

        proxy_cache_valid any 1d;

        proxy_cache_key    $uri;

        proxy_cache_purge PURGE from all;

        }

}

upstream spaz.org {

server spaz.org;

}

Is this a known issue, and what is the status?
