Issue/Introduction

Your observed an unusual behavior with the  EPAgent running on our Layer7 API Gateway (versione 11.0).

After performing a restart of the EPAgent service using the following commands:

systemctl stop epagent

systemctl start epagent

the CPU usage, which is normally stable around 20%, immediately jumps to about 50%.

The CPU then remains at this high level for several days before it gradually decreases back to the previous stable value (~20%).
