there is silver sand |

Fixer |
that has some similarities to snow |

snow texure looks nice in snow biome, it does not resemble sand to me |

VanessaE: Have just seen https://daconcepts.com/vanessa/hobbies/minetest/stats-weekly.html when looking through the last days IRC log |
| 21:01 |
VanessaE |
millersman: migrating to a new server. |
| 21:01 |
VanessaE |
stats tracking (along with most everything else :P ) was offline for a while |
| 21:02 |
millersman |
You said that Zeno` thinks that it comes from the liquid queue |
| 21:03 |
VanessaE |
OH |
| 21:03 |
millersman |
If the spikes are still of interest I doubt that they come from the liquids queue |
| 21:03 |
VanessaE |
well everything between 13:00 and 21:00 in today's stats is invalid |
| 21:03 |
Fixer_ |
did some benchmarks today on 4061: 1 hr of walking on land/sea (https://i.imgur.com/7n8tdz6.png) and 1hr underground (https://i.imgur.com/SASeYaB.png) |
| 21:03 |
VanessaE |
look at the weekly log instead |
| 21:03 |
VanessaE |
(or the monthly one) |
| 21:03 |
VanessaE |
you can see the general pattern there |
| 21:05 |
Fixer_ |
millersman: the way i measured queue size I doubt it increases, it has tendency to go to 0 |
| 21:05 |
Fixer_ |
but i'm not expert in code |
| 21:05 |
VanessaE |
the only other thing I can think of that can cause that pattern is the log files (which are stored in /dev/shm), but those account for 3 GB or so in total, not the 1-2 GB shown on the graph |
| 21:06 |
millersman |
i've never seen values in singleplayer above 50000 (seldom above 20000 and that only in extreme situations with badly optimized code), normal would be 2000 |
| 21:06 |
Fixer_ |
VanessaE: i wonder if it is possible to disable liquids at all on your server :} |
| 21:07 |
Fixer_ |
millersman: even 15000 is raare |
| 21:07 |
Fixer_ |
look my results |
| 21:07 |
millersman |
even asuming that we have 100 players on a server and 50000 liquid-queue entries for each of them that would mean 5 mio entries, which is 40 MB of memory |
| 21:07 |
lhofhansl |
paramat: did #4826 fix the rendering issues you have reproduced? |
| 21:07 |
Fixer_ |
on land, avg: 488, median: 267, mode: 0 |

deep caving (mining, exploring, digging at fast pace), avg: 1099, median: 575, mode: 0 |
| 21:08 |
millersman |
this is why i doubt that the liquid queue could be the reason, except for when there is something awfully broken in it just keeps increasing |
| 21:09 |
Fixer_ |
queue does not increase to me at all if i measured correctly, it dies down quickly to 0 in most cases even after 1hr |
| 21:11 |
Fixer_ |
millersman: biggest servers I see had 50 players at most |
| 21:12 |
Fixer_ |
millersman: and vanessas once are like <10 players or even empty |
| 21:12 |
|
troller joined #minetest-dev |
| 21:12 |
VanessaE |
then I guess the liquid queue is no longer a concern |
| 21:12 |
Fixer_ |
VanessaE: i wonder... does mem usage increases even for idle servers without players? |
| 21:13 |
paramat |
lhofhansl, i might test the fix later |
| 21:13 |
Fixer_ |
after 1hr of nonstop play my minetest game have not used anything suspicious in terms of ram |
| 21:13 |
VanessaE |
Fixer_: yes. |
| 21:13 |
VanessaE |
it's probably just the log files. |
| 21:13 |
lhofhansl |
Definitely fixed the rendering issues I've seen. |
| 21:13 |
VanessaE |
I'll move them back to disk (since it's SSD now) |
| 21:13 |
Fixer_ |
VanessaE: then liquids are not in queue? since nothing is loaded? |
| 21:14 |
millersman |
VanessaE Fixer_: I would suspect some kind of memory leak, I've seen that some servers I've been playing on got extremely unresponsive after some time |
| 21:16 |
millersman |
I've been analyzing some of the mods and there is some very memory hungry stuff in some, but nothing that accounts for GBs. But I wouldn't be supprised if some mod is collecting references to unused objects that get leaked that way |
| 21:19 |
paramat |
lua mapgens can have very high memory use, there are some optimisations that many do not yet use |
| 21:19 |
millersman |
which reminds me that i wish there was some way a mod could attach extra data to a block or even a node-address that would be managed by the database... |
| 21:20 |
Fixer_ |
millersman: how long ago? that problem with server stall was fixed |
| 21:21 |
millersman |
sometime around july/august or so |
| 21:21 |
millersman |
haven't been playing a lot lately and nothing on servers |
| 21:22 |
millersman |
so it's likely fixed |
| 21:25 |
Fixer_ |
millersman: server stall was very evident on ESM City (bigger and bigger lag with time) |
| 21:26 |
millersman |
not sure which server it was but the bigger and bigger lag with time is exactly what i've observed |
| 21:26 |
Fixer_ |
millersman: yes, that was fixed by this https://github.com/minetest/minetest/issues/4171 |
| 21:29 |
millersman |
ah ok... interesting stuff, haven't been doing a lot with networks in recent time |
| 21:32 |
millersman |
so only worked around? maybe something i could dive into when i have more time again... |
| 21:34 |
millersman |
regarding memory usage, i don't have that much experience with lua, is there a way to isolate objects allocated by the different mods in any way? |
