Team,
I am facing an issue while installing INJI Certify, where the server CPU utilisation consistently reaches close to 100%.
Upon initial investigation, it appears that the process dnsmasq may be contributing to the high resource consumption. I monitored the system using the top command and observed unusually high CPU usage across multiple intervals. Relevant excerpts are shared below:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
89661 dnsmasq 20 0 521916 270136 3632 S 83.3 13.4 33:13.08 mysql
89661 dnsmasq 20 0 521916 270136 3632 S 91.7 13.4 9:46.46 mysql
87611 root 20 0 2569112 196608 22576 S 41.7 9.8 0:36.72 java
87630 root 20 0 2083104 194676 20420 S 41.7 9.7 0:36.64 java
87420 dnsmasq 20 0 61792 22560 18252 S 8.3 1.1 0:00.38 redis
It appears that this process intermittently consumes up to 90% of CPU resources, particularly during periods when application load is otherwise low (e.g., when Java processes are not heavily consuming resources). This behaviour suggests the presence of a potentially rogue or misconfigured process.
Request you to kindly review this issue and advise on the cause and possible resolution.
Looking forward to your guidance.
Best Regards,
