Hello, In our PRODUCTION infrastructure, on Centos7 with kernel 3.10, we have manually compiled HAProxy v1.8.12 with LUA v5.3.4 It cooperates with Consul (https://www.consul.io/) via consul-template ( https://github.com/hashicorp/consul-template) to have properly, dynamically configured configuration in an haproxy.conf file (it is reloaded around 100 times per day) Everything seems to work fine and the environment is stable... but I notice that sometimes the haproxy.service commits huge amount of memory - around 20GB when only 8GB is on the host.
The value from /proc/meminfo looks something like below: Committed_AS: 20543476 kB But the strange thing is that it only uses around 1GB of RAM. I could live with that but unfortunately I do not know whether the haproxy will not take those 20GB and crash the production system because of "lack of memory" (only 8GB is available). My question is: is it normal? Do I have to be worry that this process will someday take more than 8GB of RAM? How to prevent it?
