Since you're using a older version of ModSecurity, a normal piece of advice would be to upgrade; there were at least some memory problems fixed between v3.0.4 and v3.0.5.

However, in this case, I assume you are simply triggering previously-reported issues around memory leaks when nginx rule reload is performed without a restart. See for example #2552
