Thanks for the heads up, sorry I did not check the forums before going to sleep Here's the crash report:

Looks like "udp" was null again.

So, this guy is back. Seen it a couple times the last week, likely because there are more visitors now. Same scenario; I'm watching 1 player in particular continually go back to character select, over and over. I am sure they'll not bother reporting their experience, so I can only conclude they are either crashing, or purposely camping to mass-create their menagerie of characters.

Either way, I'm suspecting the camping/coming back again. Xinux thought he found a disconnect timer, but I am wary to lower it out of fear of causing unintentional drops. If anyone is bored, it would be nice to take another look at this stack (though the line #'s have changed) to see if we can at least add logging to see what's going on.

This is incredibly disruptive, especially when we had 6 player connected trying things out, and now we have none

If we don't stop these crashes, we'll stop having testers.

Ok I think I narrowed it down to this section.

You have this function

Code: Select all

void UDPServer::KickDupeClients(uint32_t account_id, uint32_t connection_id) {

Which run this on line 285

Code: Select all

auto chunk_client = character->GetCurrentChunk()->GetClient(world_client->GetAccountID());

When it hits GetClient it goes here.

Code: Select all

shared_ptr<Client> ChunkServer::GetClient(uint32_t account_id) {
	LogInfo(LOG_CHUNK, 0, "ChunkServer::GetClient Account_id = %i", account_id);
    return udp.GetClient(account_id);
}

And then it run's this and seem's to crashes on m_clients.ReadLock();

Code: Select all

shared_ptr<Client> UDPServer::GetClient(uint32_t account_id) {
	LogInfo(LOG_UDP, 0, "UDPServer::GetClient Account_id = %i", account_id);
    
	shared_ptr<Client> client;
	
	LogInfo(LOG_UDP, 0, "UDPServer::GetClient shared_ptr");
   
	m_clients.ReadLock();
	
	LogInfo(LOG_UDP, 0, "UDPServer::GetClient ReadLock Account_id = %i", account_id);
   
	for (auto& itr : clients) {
        if (itr.second->GetAccountID() == account_id && itr.second->IsConnected()) {
            client = itr.second;
            break;
        }
    }
    m_clients.ReadUnlock();
	
	LogInfo(LOG_UDP, 0, "GetClient Return Client Account_id = %i", account_id);
    
	return client;
}

Code: Select all

20:40:55.796 I UDP      KickDupeClients Account_id = 1 Connection_id = 543107592
20:40:55.798 I UDP      KickDupeClients Readlock Account_id = 1 Connection_id = 543107592
20:40:55.799 I UDP      KickDupeClients ReadUnlock Account_id = 1 Connection_id = 543107592
20:40:55.800 I UDP      KickDupeClients before auto chunk_client
20:40:55.801 I Chunk    ChunkServer::GetClient Account_id = 1
20:40:55.802 I UDP      UDPServer::GetClient Account_id = 1
20:40:55.802 I UDP      UDPServer::GetClient shared_ptr

I'm almost thinking the issue is if there is multiple of the same account it's getting confused. I'm going to post in private on how to get the server to crash every time.

Ok just committed a fix for this hopefully since i cannot reproduce the crash i was able to reproduce 99% of the time.
