Game core problem

[regal 26]

Hello, I have a game.core issue with my server.

Every now and then(some time the server runs ok for 2 days for ex), sometimes after 1 day maybe I get a core crash.

I attached a screen from bt

If anyone can help me i would be grateful.. maybe someone encountered similar issue

 

Desc handshake code from desc.pp

 

bool DESC::HandshakeProcess(DWORD dwTime, long lDelta, bool bInfiniteRetry)
{
	DWORD dwCurTime = get_dword_time();

	if (lDelta < 0)
	{
		sys_err("Desc::HandshakeProcess : value error (lDelta %d, ip %s)", lDelta, m_stHost.c_str());
		return false;
	}

	int bias = (int)(dwCurTime - (dwTime + lDelta));

	if (bias >= 0 && bias <= 50)
	{
		if (bInfiniteRetry)
		{
			BYTE bHeader = HEADER_GC_TIME_SYNC;
			Packet(&bHeader, sizeof(BYTE));
		}

		if (GetCharacter())
			sys_log(0, "Handshake: client_time %u server_time %u name: %s", m_dwClientTime, dwCurTime, GetCharacter()->GetName());
		else
			sys_log(0, "Handshake: client_time %u server_time %u", m_dwClientTime, dwCurTime, lDelta);

		m_dwClientTime = dwCurTime;
		m_bHandshaking = false;
		return true;
	}

	long lNewDelta = (long)(dwCurTime - dwTime) / 2;

	if (lNewDelta < 0)
	{
		sys_log(0, "Handshake: lower than zero %d", lNewDelta);
		lNewDelta = (dwCurTime - m_dwHandshakeSentTime) / 2;
	}

	sys_log(1, "Handshake: ServerTime %u dwTime %u lDelta %d SentTime %u lNewDelta %d", dwCurTime, dwTime, lDelta, m_dwHandshakeSentTime, lNewDelta);

	if (!bInfiniteRetry)
		if (++m_iHandshakeRetry > HANDSHAKE_RETRY_LIMIT)
		{
			sys_err("handshake retry limit reached! (limit %d character %s)",
				HANDSHAKE_RETRY_LIMIT, GetCharacter() ? GetCharacter()->GetName() : "!NO CHARACTER!");
			SetPhase(PHASE_CLOSE);
			return false;
		}

	SendHandshake(dwCurTime, lNewDelta);
	return false;
}

 

P.S. : I can pay if needed, king.s.prod on discord. Thank you

Might help:

 

bool DESC::HandshakeProcess(DWORD dwTime, long lDelta, bool bInfiniteRetry)
{
	DWORD dwCurTime = get_dword_time();

	if (lDelta < 0)
	{
		sys_err("Desc::HandshakeProcess : value error (lDelta %d, ip %s)", lDelta, m_stHost.c_str());
		return false;
	}

	int bias = (int) (dwCurTime - (dwTime + lDelta));

	if (bias >= 0 && bias <= 50)
	{
		if (bInfiniteRetry)
		{
			BYTE bHeader = HEADER_GC_TIME_SYNC;
			Packet(&bHeader, sizeof(BYTE));
		}

		if (GetCharacter())
			sys_log(0, "Handshake: client_time %u server_time %u name: %s", m_dwClientTime, dwCurTime, GetCharacter()->GetName());
		else
			sys_log(0, "Handshake: client_time %u server_time %u", m_dwClientTime, dwCurTime, lDelta);

		m_dwClientTime = dwCurTime;
		m_bHandshaking = false;
		return true;
	}

	long lNewDelta = (long) (dwCurTime - dwTime) / 2;

	if (lNewDelta < 0)
	{
		sys_log(0, "Handshake: lower than zero %d", lNewDelta);
		lNewDelta = (dwCurTime - m_dwHandshakeSentTime) / 2;
	}

	sys_log(1, "Handshake: ServerTime %u dwTime %u lDelta %d SentTime %u lNewDelta %d", dwCurTime, dwTime, lDelta, m_dwHandshakeSentTime, lNewDelta);

	if (!bInfiniteRetry)
		if (++m_iHandshakeRetry > HANDSHAKE_RETRY_LIMIT)
		{
			sys_err("handshake retry limit reached! (limit %d character %s)",
					HANDSHAKE_RETRY_LIMIT, GetCharacter() ? GetCharacter()->GetName() : "!NO CHARACTER!");
			SetPhase(PHASE_CLOSE);
			return false;
		}

	SendHandshake(dwCurTime, lNewDelta);
	return false;
}

Fixed, the problem was from map_allow_limit.

Even if you don't have more than 30 maps for core, if you have multiple channels you will start getting problems.

Increasing the map_allow_limit fixed the issue.
