MGR having slow connection

Overview

A particular MGR is having slow connection, i.e. loading of pages and execution of some action is slow, along with high Memory or CPU utilization (almost 90%).

Solution

You should have access to MGR GUI and SSH Access to MGR

1. SSH into MGR node and check the resources utilization (as root):
   
   top
   free -h
   df -kh
   
   Generally CPU or Memory utilizations come out to be high (more than or around 90%)
   
   

2. Reboot MGR node (as root)
   
   reboot now
   
   (CAUTION! Rebooting the server will get MGR service down for some time, but would NOT impact the SMS traffic.)
   
   

3. Once the server comes up, verify all services are running fine (As textpass)
   
   systemctl status mgr
   stv_db_importer --status
   stv_poll_collector --status
   stv_poll_config _sync --status
   stv_poller --status
   
   

4. Start the services if they are down
   
   systemctl start mgr
   stv_db_importer --start
   stv_poll_collector --start
   stv_poll_config _sync --start
   stv_poller --start

Testing

1. Check the Memory and CPU utilizations (as root), which should be quite low than earlier
   
   top
   free -h
   
   

2. Login to MGR and verify if MGR is responding well now

3. If the problem is not resolved, please contact Newnet support with:
   1. Any particular date/time when it was noticed that this issue started?
   2. Provide output of (as root)
      1. free -h
      2. df -kh
      3. mysql -uroot -pPassword -e "show full processlist"
      4. su - textpass -c tp_status
   3. Kindly attach /var/log/messages
      1. /var/TextPass/MGR/tp_mgr_change_log.txt
      2. /var/TextPass/MGRtp_mgr_error_log.txt
