Hi. I use this test-code for Swap Players teams:

PHP Code:

#include <amxmodx>
#include <cstrike>
#include <fun>
#include <fakemeta>

public plugin_init()
{
    register_plugin("Test", "0.1", "Phantomas")
    register_clcmd("say t", "clcmdT");
}

team_swap(id, CsTeams:team)
{
    if(team == CS_TEAM_T)
    {
        //cs_set_user_team(id, CS_TEAM_CT, CS_DONTCHANGE)
        set_pdata_int(id, 114, 2)
    } else {
        //cs_set_user_team(id, CS_TEAM_T, CS_DONTCHANGE)
        set_pdata_int(id, 114, 1)
    }
}

public clcmdT(id)
{
    new players[32], pnum, plr
    get_players(players, pnum, "h")
    for (new i; i<pnum; i++)
    {
        plr = players[i]
        new CsTeams:team
        team = cs_get_user_team(plr)
        if(team == CS_TEAM_T || CS_TEAM_CT) {
            team_swap(plr, team)
        }
    }
} 


And when I test it on server with ~10 players (5x5), it's okay, all works fine.
But when server have more players (I test 16x16 with PODBots), then server crashed at new round start moment (after swapping):

SZ_GetSpace: overflow without FSB_ALLOWOVERFLOW set on Server Reliable Datagram

Any ideas how to bypass it? cs_set_user_team() got crash too.

This code exactly can't crash the server but you do that before all players are spawning for example, yes, it's the cause.

Long short story, this error is an engine bug which doesn't check for buffer overflow. It happens when too much players need to update the model.

Native has been fixed in dev build, fix is essentially that any update is always postponed at the next frame, so the engine buffer doesn't overflow.

So, bypass: Change team with some delay, for example:

PHP Code:

#include <amxmodx>
#include <cstrike>
#include <fun>
#include <fakemeta>

public plugin_init()
{
    register_plugin("Test", "0.1", "Phantomas")
    register_clcmd("say t", "clcmdT");
}

public swap_teams(id)
{
    switch(cs_get_user_team(id))
    {
        case CS_TEAM_CT:cs_set_user_team(id, CS_TEAM_T);
        case CS_TEAM_T:cs_set_user_team(id, CS_TEAM_CT);
    }
}

team_swap(id)
{
    switch(id)
    {
        case 1..7: set_task( 0.2, "swap_teams", id );
        case 8..15: set_task( 0.4, "swap_teams", id );
        case 16..23: set_task( 0.6, "swap_teams", id );
        case 24..32: set_task( 0.8, "swap_teams", id );
    }
}

public clcmdT(id)
{
    new players[32], pnum, plr
    get_players(players, pnum, "h")
    for (new i; i<pnum; i++)
    {
        plr = players[i]
        team_swap(plr)
    }
}
