colossal chest nbt size problem
charchess opened this issue · 24 comments
Hi,
am running a server 1.10.2 - forge 12.18.1.2071 with lots of mods and I came accross a problem with colossal chest twice
I had a 4x4x4 chest, full, tried to expand it to 5 and it came with some nbt size problem limit. I did accept the situation and started a new server.
I came across another similar problem but client side, chest being heavily loaded (5x5x5) it said io.netty.handler.timeout.readtimeoutexception:java.lang.runtimeexception: tried to read NBT tag that was too big;tried to allocate: 2097158 bytes where max allowed: 2097152.
removed colossa chest and was able to log on ...
for your information, I came across a problem today involving botania/storage drawer soooo ... maybe it's botania who has an issue... just feel I'd let you know and maybe double checking the nbt memory usage when the chest is heavily loaded ?
feel free to ask if you need something (or close this ticket if you don't think CC may have a problem)
oh ...and keep up the good work, this mod really is nice

I anticipated that this might happen. That is why I added the maxSlotsPerPacket option in the config file. Try decreasing this value, and see if this your problem. Let me know which value worked for you, and I'll use that as default value for the next update.
sadly I am not sure I still have the backup of the server in that state, will double check and let you know/do some tries
sorry, don't have the backup anymore and moved to mc 1.7.10 due to lag on server and some non compatible mods I wanted to add.
If I ever come accross the same problem on another server, I'll keep you in touch
this is still happening, we've lowered the config option to 1500 and rasied to 3500..we've tried everything..it's happening on a silver chest which has 9k+ slots..I'm assuming you're storing all of this in a single TE..a better idea that would significantly decrease NBT size would be to create custom slots which allow for more then 64 item per slot..I do this with the /dank/null
I've been thinking about this, and I could do something about this by not using a fixed, but a dynamic fragmentation of NBT. Will probably require some hacking around some Vanilla code though...
Im now myself getting this error although slightly different with a 6x6 Colossal Diamond Chest thats not even 1/4 full..Im now stuck and unable to join world and have the chest actively loaded without getting error again.
Im downgrading verion by version untill i can successfully re-join an remain joined and i'll post which version it is.
All release vers on Curse are no good, now trying the dev builds you have listed
@Morpheus1101 Ok, interesting, so you're encountering a special case that has never worked before.
I suspect an ItemStack that has a very large NBT tag somewhere in the chest, is that possible?
(No need to test the other dev builds btw, if the releases don't work, the later dev builds won't work either)
tbh i couldnt tell you, since ive prev not encounted this prior to today, im not even sure how to find out
There are some things I could try, but that won't be before Sunday unfortunately.
Note to self: Double-check to make sure chunk load packet for TE's doesn't send inventory data to clients.
Thats ok, this new MMD-Dev pack isnt going live for a few weeks yet, its just intial testing to work out easy found crashes an bugs :)
Actually i suspect this isnt actually your mod thats causing it, well not directly anyway, i believe it maybe HoloInventory thats causing the problem, which im about to test, as i suspect that mod dosent have support etc for the size of colossal chests and when going to display the items contained in the chest, is when the NBT error occurs..
ok unf with that mod disabled it didnt solve it and i was really sure it would lol
@Morpheus1101 It could be that another mod may be causing this as well. Perhaps you could try disabling other mods as well, as far as that's possible.
@Morpheus1101 Ok, one of those obscure cross-mod issues then. Good to know, and thanks for letting me know :)
Ok, so after further discussion with another another modder we've discovered the issue to be caused by a mod called Cyclic which seems to trigger a bug in IC2 ... so thankfully this wasnt an issue with Colossal Chest :D
I've run into what appears to be the same problem, or closely related. See FTB Forum for some reports. Looking at the interface block on a chest has started crashing the app, and the logs mention NBT size limit being exceeded. It looks like maxSlotsPerPacket was replaced with maxPacketBufferSize; I tried setting that to 10000 and still crashed.
In my case I've got a 7x7x7 wood chest a little over 50% full, and the single interface block as a Refined Storage storage interface attached to it. This is in the Sky Factory 3 mod pack. My setup had been working fine until I upgraded Sky Factory to 3.0.6. I don't know if there are any usual items in my chest; they're pretty much the same items I had before the upgrade. Later tonight I'll probably look into removing things to see if that helps, but trying to identify a particular item that's a problem isn't going to be feasible, with so many items in storage.
@dougwebb If it only crashes when looking at the interface block, it sounds like an issue with a mod like WAILA that sends the complete inventory to the client, which shouldn't happen. I suggest you identify that mod and report it to their issue tracker.
Can successfully still reproduce the crash. In this particular case, I've been able to solve it by turning off WAILA (numpad 1).
