Symptoms

When I attempt to view the application log in the console, the following error message appears: An error occurs when I run a command in the Star Agent command channel.

Causes

This Elastic Compute Service (ECS) instance is overloaded due to an excessive number of requests. As a result, the following error occurs when you run a command to view the log: exit 125, su: cannot set user id: Resource temporarily unavailable. For more information, see https://access.redhat.com/solutions/30316.

Solutions

  1. Restart the ECS instance as the first option.
  2. Configure the /etc/security/limits.d/90-nproc.conf file. Increase the connections to the highest settings before you restart the ECS instance.
  3. Check whether the 8182 port of the ECS instance has been blocked by the firewall.
  4. If the error persists after the preceding steps, contact Enterprise Distributed Application Service (EDAS) technical support.
