MaxReqsInQuery do not work ?

Hello, In shared.properties file, we have changed the parameter "MaxReqsInQuery" from 1000 to 20000. We have restarted the server. When we do a selectQuery like rbv_api.selectQuery("SELECT id FROM xxx", 5000), Rollbase still returns no more than 1000 records. The "MaxReqsInQuery" parameter seems to be stucked/blocked at 1000, even if we change the value. We have changed the "MaxCachedEntities" parameter too but still it does not change anything. We don't see where this problem come from. Can you help ? Thank you. Matthieu
