Function invocation limit
CONFIG PARAMETER: function_invocation_limit <num>
This directive sets the maximum number of times that a command may make function calls. If the invocation limit is exceeded, the string '#-1 FUNCTION INVOCATION LIMIT EXCEEDED' is returned. This limit is intended to prevent long hangs from creative uses of u() and iter(). Note: @search is treated specially, each object examined with the eval=<arg> parameter is treated as a separate command for the purposes of the function invocation limit.
