Title: 26+ players server crash
Post by: RMF on October 15, 2009, 01:28:01 AM

I got this eversince I run servers, but it never was a real problem. But now I want to organise a big match (for OAchallenge (http://oachallenge.webs.com)) where probably will me more players than my 26 limit. This is a part of the console log when testing with some bots:

Because it couldnt allocate the space I tried making the memory space bigger (com_hunkmegs;soundmegs;zonemegs all doubled or more), but that doesn't help. I got 3GB RAM at home, and where I just tried 4GB so that's not the problem.. Anyone another idea?

Btw I think it's possible because I saw ROFL|chatroom has 42 slots. Never seen it filled up though (once 20 or something, never more)..

Thanks in advance for any help :)

It seems the G_Alloc() memory is hard-coded at 256K and cannot be changed by console vars. You would have to compile your own qvms.

From code/game/g_mem.c :

Code:

#define POOLSIZE    (256 * 1024)

static char     memoryPool[POOLSIZE];
static int      allocPoint;

void *G_Alloc( int size ) {
    char    *p;

    if ( g_debugAlloc.integer ) {
        G_Printf( "G_Alloc of %i bytes (%i left)\n", size, POOLSIZE - allocPoint - ( ( size + 31 ) & ~31 ) );
    }

    if ( allocPoint + size > POOLSIZE ) {
      G_Error( "G_Alloc: failed on allocation of %i bytes\n", size ); // bk010103 - was %u, but is signed
        return NULL;
    }

    p = &memoryPool[allocPoint];

    allocPoint += ( size + 31 ) & ~31;

    return p;
}

There isn't anything special on Chatroom, fill it and that'll explode ;)

Bots require more memory than normal clients. G_Alloc is only used on bots.

As soon as this is fixed i am going to run a splatter server, with 63 lowrank bots and only big maps haha

i think since the "128Mb is lots of mem" 1999 Q3 era, we can have more than 256K reserved for this how about 1M? 26*4 = 104 players (should be enough for everyone).

I heard from DSD that only bots alloc this mem, with so many client connecitons it did not crash.

We probably don't reach 104 players online on average so 100 player spots should be enough :P

maybe we can have way bigger maps that could support bigger player numbers?
I think it would be fun, if the server and network dont lag too much because of the amounts of information transmitted.
