Suricata memory usage has been increasing, look like memory leak.
Env: REHL 7.8, Linux kernel is 3.10.0-1127, suricata version is 7.0.0-dev. use with pfring. IDS mode.
tcp.memuse - 1.8gb
tcp.reassembly_memuse - 33.4gb
http.memuse - 1.9gb
flow.memuse - 1.9gb
The suricata process start in 12/23 2021. It has been running for 6 days now.
In 12/24, it’s memory usage is 21gb. But the memory usage has been increasing to now 47gb.
The traffic is 3gbps.
I just want to know how much memory can satisfy it.
My cpu is 40 logic core. And config suricata about 20 work thread. And the cpu usage is less than 10%.
Hope to get a reply, thank you!
