- Implementation of ScheduledSSLFIXServer, which accepts secure SSL/TLS connection and supports timetables for FIX sessions is available out of the box.
Bugs and fixes:
- FIX session with no-queue sending mode might send a bunch of messages with higher than expected MsgSeqNum(34) right after reconnect.
-
- Problem description: FIX session with no-queue sending mode didn't wait for the finish of sequences synchronization procedure and started to send application messages immediately after Logon message. It might lead to sending a bunch of messages with sequence numbers higher than expected and receiving o lot of ResendRequests(2) from others side.
- Solution: Awaiting for an answer from the other side after reconnect during some reasonable period was introduced.
