Too low memory on your system, it can't allocate a new character pointer.

but how? future of my system is very good i think.

I dont know about ur serverfiles but that mysql usage is very bad.

Try add more ram.Clear logs.

I know. But i dont know what uses mysql. My server files contains scirred offline shop and official pet system and they rape mysql i think. All log tables disabled already.

I dont know if cluster will help.But maybe are to many calls to the same table.Spliting DB will help but i never did that.

Check this topic :

Check the log of mysql, maybie they say who's accessing mysql.

i activated general_log and slow_query_log but there is nothing.

when i check on my test server i realized that i warp any map and mysql usage goes up to %4 usage. And after 10 seconds it goes down to 0.

edit: when i activated mysql logs, there is not general_log table. i created manually.

add

log-queries-not-using-indexes

to my.cnf
and run mysqltuner on server

thanks for reply. i dont need mysql log anymore because i found what causes high usage of mysql.

i used this query when i warp and when i close shop.

select * from INFORMATION_SCHEMA.PROCESSLIST where db = 'player'

i found that when i warp and when i close my shop there is a control on mysql and it causes high mysql usage.

now i have to modify this code. thanks all for your help up to here. any idea how i modify this code?

this code is:

void CHARACTER::RefreshGift()
{
	char szSockets[1024] = { '\0' };
	char *tempSockets = szSockets;
	for (int i = 0; i < ITEM_SOCKET_MAX_NUM; i++)
	{
		tempSockets += sprintf(tempSockets, "socket%d", i);

		if (i<ITEM_SOCKET_MAX_NUM - 1)
			tempSockets += sprintf(tempSockets, ",");
	}
	char szAttrs[1024] = { '\0' };
	char *tempAttrs = szAttrs;
	for (int i = 0; i < ITEM_ATTRIBUTE_MAX_NUM; i++)
	{
		if (i < 7)
			tempAttrs += sprintf(tempAttrs, "attrtype%d,attrvalue%d", i, i);
		else
			tempAttrs += sprintf(tempAttrs, "applytype%d,applyvalue%d", i - 7, i - 7);
		if (i<ITEM_ATTRIBUTE_MAX_NUM - 1)
			tempAttrs += sprintf(tempAttrs, ",");
	}
#ifdef __CHANGE_LOOK_SYSTEM__

#else
	SQLMsg * pkMsg(DBManager::instance().DirectQuery("SELECT id,vnum,count,unix_timestamp(date_add),replace(reason,' ','_'),replace(`from`,' ','_'),%s,%s from player_gift where  owner_id = %d and status = 'WAIT' ORDER BY date_add ", szSockets, szAttrs, GetPlayerID()));
#endif
    SQLResult * pRes = pkMsg->Get();
	m_mapGiftGrid.clear();
	grid = M2_NEW CGrid(15, 8);
	grid->Clear();
	int page = 1;
	if (pRes->uiNumRows>0)
	{
		AddGiftGrid(page);
		MYSQL_ROW row;
		while ((row = mysql_fetch_row(pRes->pSQLResult)) != NULL)
		{
			int col = 0;
			TGiftItem item;
			memset(&item, 0, sizeof(item));
			str_to_number(item.id, row[col++]);
			str_to_number(item.vnum, row[col++]);

			for (int i = 0; i < ITEM_ATTRIBUTE_MAX_NUM; i++)
			{
				str_to_number(item.aAttr[i].bType, row[col++]);
				str_to_number(item.aAttr[i].sValue, row[col++]);
			}
#ifdef __CHANGE_LOOK_SYSTEM__
			str_to_number(item.dwLookVnum, row[col++]);
#endif

			const TItemTable * item_table = ITEM_MANAGER::instance().GetTable(item.vnum);

				continue;
			int iPos = AddGiftGridItem( page, item_table->bSize);
			if (iPos < 0)
			{
				page++;
				grid->Clear();
				iPos = AddGiftGridItem(page, item_table->bSize);

i dont know why the code which is above causes %4 mysql usage for every player. How this query cause? The website also has sorting query but it doesn't increase mysql usage for example. Do you have any idea?

Edit: I think i solved problem. Thanks all for your help. I just added indexes my player_gift table with following code. Now mysql usage is OK.

ALTER TABLE player_gift ADD INDEX episode_active(owner_id, status);

Mysql usage is OK. But core crashes randomly because of the same problem.

Help pls. What can cause this crash?

If you disabled the log tables that will cause mysql high usage. If you want to disable log table do it from source, but let the table work like : disable the change bonus on item because it loads the table a lot.

Siccred offline shop doesn't have anything releated with your 170% mysql usage.

Scirred offline shop related with high mysql usage because every warp and in every 5 minutes there is a mysql search for every players. So i solved with adding indexes to player_gift table and mysql usage is OK now. My problem is not mysql usage my problem is core crash which tells me that bad memory alloc. Although i have enough ram my cores crash randomly in a few days. I just wanted to learn that if someone faced a problem like this. It can be because of adding a system like transmutaion, new pets or just because of freebsd 10.3. I already disabled log tables from source.

Your main problem of getting crash is that mysql usage. Fix it.

I fixed it. Mysql usage is %3-10 now. Crash problem is still exist. I said that i fixed mysql problem many times.

Speachless · April 1, 2017

I remembered now a friend had a problem because with map index, and you have map index 660141 ? Change your map index to something like 223. That's how he solved.

I be damned if this isn't the problem.
