Description

Root cause

- SWAP usage exceeds 50%, triggering the restart mechanism for the ATCP process.

- Analyzing the monitor log shows that lighttpd’s memory usage is abnormally high, and SWAP usage increased prior to the event.
Solution

- Upgrade the third-party package lighttpd from version 1.4.54 to 1.4.76, which is currently stable on EL10.

- Maintain lighttpd 1.4.76 on EL7 by creating an RPM package.

Testing Done

- Start the services with "webui on", "restapi on http" and "restapi on http", and test whether they are functioning properly.
- At "restapi on http" and "restapi on https", use a command to check the lighttpd version.
  "curl -I -k <http/https>://<ip>:<port>"
  show Server: lighttpd/1.4.76
