Error symptom: Check the application log in the EDAS Console. The message "An errors occurs when the StarAgent command pipeline runs a command" is returned.
The first possible reason is that the host is heavily loaded and the number of requests is too large. As a result, the error message "exit 125, su: cannot set user id: Resource temporarily unavailable" is returned when the log query command is run.

Restart the host. If the fault persists, modify the number of connections in the /etc/security/limits.d/90-nproc.conf file to a greater value, and restart the host.
If the fault persists, check whether the firewall disables port 8182 of the ECS server.
If the fault persists, contact Alibaba Cloud technical support.
