This function is from my UT style weapon floating plugin. It works fine on every map I have except airstip. I have it set to execute the above statement ONCE from plugin_init in a test plugin. that's all that happens. It executes once and no other 3rd party plugin is running. Here is the log i get out:

L 10/09/2007 - 13:18:06: [GHW_Floating_Weapons.amxx] Start
L 10/09/2007 - 13:18:06: [GHW_Floating_Weapons.amxx] 34
L 10/09/2007 - 13:18:06: [GHW_Floating_Weapons.amxx] (Lots of ent numbers)
L 10/09/2007 - 13:18:06: [GHW_Floating_Weapons.amxx] 407
L 10/09/2007 - 13:18:06: [GHW_Floating_Weapons.amxx] 34
L 10/09/2007 - 13:18:06: [GHW_Floating_Weapons.amxx] (Lots of ent numbers)
L 10/09/2007 - 13:18:06: [GHW_Floating_Weapons.amxx] 407

The end is never printed into the log file. It appears that this:

engfunc(EngFunc_FindEntityInSphere,407,Float:{0.0,0.0,0.0},4800.0)

is returning 34... I had like 2 hours of sleep a couple days ago so I think it could be a typo of some sort but I really don't know... and I don't know why it only happens on airstrip...

There is some weird infinite loop going on for that map

I had very funny problems with sphere functions. Honestly, I set it up to search entities in radius of 128 units from player's origin. Then I calculated distance from found entity. In most cases, it was below 128 but in some, it found entities even further (much further).

Have you tried cs_siege?

de_torn crashes my server as well.

I ran your snippet on several maps, including airstrip and torn, and didn't have any problems.
I did add a client command

register_clcmd("say /spin", "force_spin", 0, "Spins ents")

so I could control the spin manually. Also, I moved the

log_amx("%d",ent)

statement to after the compare as to not print out all the unecessary entities.

[GHW_Chronic]

well then it is clear that there is some variable different between the two of us that stops this line of code from working properly.

me:
listenserver
windows
AMXX 1.8
no 3rd party plugins

[Vet]

I ran it on:
Dedicated server on LAN
Windows XP
Amxx 1.8
Lots of other plugins

Weird.

[Vet]

Here's the sma of the routine I used. Just "say /spin" and the weapons rotate and the log looks OK.

I always get mixed results with findentinsphere, i prefer to loop through all the ents and check the classname as its give me better results and is probably a lot more economical and less cpu than findentinsphere.
I also hate using static variables because I never get any consistance (i probably use them wrong half the time lol) so I stick with new style variables.

PHP Code:

public plugin_init()
    set_task(0.1, "force_spin", _, _, _, "b");

public force_spin()
    if (get_timeleft())
    {
        new classname[11], Float:angles[3], ent = -1, ent_total = engfunc(EngFunc_NumberOfEntities) + 30;
        while (ent++ < ent_total)
            if (pev_valid(ent))
            {
                pev(ent, pev_classname, classname, 10);
                if (containi(classname, "armoury") != -1 || containi(classname, "weaponbox") != -1)
                {
                    pev(ent, pev_angles, angles);
                    //angles[1] += get_pcvar_float(speed_pcvar) / 10.0;
                    angles[1] += 27.0;
                    if(angles[1] >= 180.0)
                        angles[1] -= 360.0;
                    set_pev(ent, pev_angles, angles);
                }
            }
    }
