Cause

sw-enginer stuck on destination server.
Resolution

Increase limit for open files:

Modify ‘/etc/init.d/sw-engine’, add the following into the startup script:


    ulimit -n 65536

Restart the services:


    #service sw-engine restart
    #service sw-cp-server restart

If Nginx alredy service stuck:

a. Kill alll nginx processes using the below command:


    # killall nginx

b. Restart nginx service:


    # systemctl start nginx.service

Disable and re-enale nginx using nginxmng:


    # /usr/local/psa/admin/bin/nginxmng -d
    # /usr/local/psa/admin/bin/nginxmng -e
    # /usr/local/psa/admin/bin/nginxmng -s
    Enabled
