I am having problems using acc.so. It seems that I can't set the following two modparams:

modparam("acc", "db_flag", 2)
modparam("acc", "db_missed_flag", 2)

But I have no problems setting these two modparams and commenting the top 2:

modparam("acc", "log_level", 1)
modparam("acc", "log_flag", 1)
