hello,

There is not too much 1GB. No, i did not disabled mode_sec.

The list of loaded modules:
load_module modules/ngx_http_brotli_filter_module.so;
load_module modules/ngx_http_brotli_static_module.so;
load_module modules/ngx_http_modsecurity_module.so;
load_module modules/ngx_http_geoip2_module.so;

this is an issue that suddenly started to come out. There always has been this config and software installed.
I think some kind of requests are causing this but does not know if it is a module or nginx itself.

Can i troubleshoot it? I mean, when the issue will pop up again, try to gather some info? if yes, how?
