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?
