I tested this lib(3.0.12) with nginx model ModSecurity-nginx on Linux platform by reloading nginx (nginx -s reload) again and again for quite a log time，and I found that the memory (RSS) still increases a little bit every several times. The more config rules, the bigger memory increases, and it will cause out of memory (OOM) reloading not more than a thousand times.
And I do read some issues like 2848 before, it seems the problem has been resolved, but I am not sure.

Here are some of my test results, and the docker env do cause OOM problem, and I don't know how that happens, could you please help me with that, many thanks.

the docker environment（more Modsecurity rules）:
