Quote: " - $var has local route block scope. - $avp has SIP transaction scope.
- Both $avp and $var are automatically freed." If I call sql_xquery( "dbConn", "SELECT * from some_table;", "ra" ); inside a rtimer route, causing $xavp(ra) to contain many rows and columns each time it's run, would the $xavp(ra) be freed, and when? Since this is done on an rtimer route for some DB maintainance rather than on a transaction created for some incoming message so I am not sure whether this will cause some memory leak. I would appreciate some hints.
