Does it work? #2

Open maximko opened 1 week ago

maximko commented 1 week ago

I'm looking for a way to extend functionality of my goip gateways with sms server. I built this docker image and found that goipcron_x64 process takes 100% of single core time, and it doesn't listening on 44444/udp (no record in netstat -nlup) Is it expected behaviour?

Found the root of the issue: for some reason there is a loop in goipcron_x64 that tries to close all file descriptors possible and in my system it's limit is very large, so closing takes forever:

root@f8c3c956be81:/# cat /proc/sys/fs/file-max
9223372036854775807

So there are two solutions:

  1. Pass -d option to goipcron_x64 executable to disable closing of all file descriptors (source)
  2. Modify docker-compose.yml to add limit: 
    ulimits:
  nofile:
    soft: 26677
    hard: 46677

    I'll make a PR if I wouldn't be lazy.
