Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Crash on server side with UE 4.17

I'm developing a client-server app. The server side creates a session and the client side joins it. Until UE 4.16 it worked well, but after the update to UE 4.17 the server side crashes once the client has joined the session.

The thing is it crashes only when using the Oculus subsystem, but still works with Null.

The error is the following:

 [2017.09.08-10.24.01:995][ 94]LogWindows: Error: === Critical error: ===
 [2017.09.08-10.24.01:995][ 94]LogWindows: Error: 
 [2017.09.08-10.24.01:996][ 94]LogWindows: Error: Assertion failed: HasReceivedClientPacket() [File:D:\Build\++UE4+Release-4.17+Compile\Sync\Engine\Source\Runtime\Engine\Private\NetConnection.cpp] [Line: 684]

So the problem is the method HasReceivedClientPacket() in the NetConnection class. This method has been introduced in UE 4.17 (it does not exist in 4.16) and this is what it does (NetConnection.h):

 FORCEINLINE bool HasReceivedClientPacket()
     return !!InternalAck || Driver->ServerConnection != nullptr || InReliable[0] != InitInReliable;

May you investigate on this problem?

Product Version: UE 4.17
