We use TREP 2.2 to get HongKong Stocks quote data for years. Our client Program use rfa7.2.1 C++. Recently we upgrade TREP from version 2.2 to 3.2. When our Program connects to TREP 3.2 at first time, we can't get any quote data until we also upgrade these three file appendix_a, enumtype.def, RDMFieldDictionary.Now we can get most HongKong Stocks's quote data. But some 170 RICs can't get quote data. In logs file, we found: Received Event Stream Closed Event, event type: OMMItemEventEnum handle: 0x2aaaaf7fab00, 3988.HK. Those logs trigger by event.isEventStreamClosed(). But on TREP server, use rsslSinkApp to get 3988.HK's quote data OK. We need help! Thanks!
