This is the ModSecurity v2 implementation of the SecArgumentsLimit configuration item, which was previously implemented in ModSecurity v3.
The limit is configurable via the new directive but there is a software default of 1000.
Exceeding the limit will set REQBODY_ERROR and additional arguments beyond the limit will not be included. With JSON body processing there is an additional short-circuit to halt parsing once the limit is breached.
