thank you @Limbooc for reply, your suggestions have been taken into account

regarding sv_restart 1 doesn t help, only mapchange have a good effect

this server is just for test but the addons from it is running on the main server(excluding updated plugins) also, but the problem is not on main server, maybe because there is timelimit 25 and map change after voting

what changed i made on test server i didn t applied them on main server for now, the main server is running the same addons since 2020, so test server same

because on test server i made bulk update for some plugins i m not sure which can be the problem(if is not 100% related to goldsrc), i will really test by deactivating hooks from plugins(one by one or at least by the last edited)

excluding your suggestion regarding sys ticrate(already 1k) and fps max(which i applied) i also increased -zone parameter to 4096 and decreased -num_edicts to 2048, also if the problem persists i will try with parameter -pingboost 2/3

regarding plugins :

default plugin = i didn t edited them

npc_bonusmon_095.amxx , animations.amxx , sex.amxx they start entity interaction only by command

models which are using flag 512 are santa form xmas_ents.amxx and vehicle model from Zephyr-G_Swoop.amxx

i think problem occured after i activated holidays plugins: random_gifts.amxx , xmas_ents.amxx , new_year.amxx , npc_bonusmon_095.amxx where random_gifts.amxx , xmas_ents.amxx can be the problem, but according to me, the code is ok....

regarding xmas_ents.amxx , here i tried to recreate manually animation with frames like this (ignore my comments from code) and if is necessary i can post full source code

@ragnarot,
This is a GoldSrc engine limitation, not something caused by plugins or server settings.

The root cause is floating-point precision loss in gpGlobals->time. The engine stores server time in seconds as a float, and float has limited precision: the larger the value becomes (the longer the server runs), the bigger the smallest time increment it can represent.
In other words, after enough uptime, float can no longer represent very small time changes accurately.

When the server runs for a long time without a map change, gpGlobals->time grows large enough that the difference between the current frame and the previous one (frametime) starts being computed with significant error - sometimes rounding down to zero, other times jumping in larger steps.

As a result, physics breaks, because the engine can’t reliably calculate object movement (velocity * frametime). That’s why entities may "freeze" in mid-air (the computed displacement becomes zero due to rounding), or clip/fall through floors and walls (collisions don’t get processed correctly when time steps become erratic).

To avoid this, change the map every 12-18 hours (or sooner). This resets the map time and prevents gpGlobals->time from growing large enough to trigger these physics issues.

did you try this on ReHLDS?

C-подобный:

sv_rehlds_local_gametime <1|0> // A feature of local gametime which decrease "lags" if you run same map for a long time. Default: 0

ragnarot · 18.01.2026

yes, it was on value 1 since it was implemented
i had a default server(rehlds, regame, remetamod, reunion, reapi, snac, amxx[def plgs]) where it was only fy_snow permanently(timelimit 0, no map change/vote nor sv_restart) and i didn t saw this problem where server was online continously more than 2 weeks

This doesn’t fix server physics. It only adjusts the client time (svc_time) to reduce float precision issues on the client side - prediction, interpolation, animations, weapondata, etc. So it can help with client‑side glitches on long uptime maps, but it won’t stop server‑side entities from freezing or falling through the world.
