TConstruct Lava Overflow Server Crash

[ThermalCraft]

Hi,

FTB Version: Unleashed, 1.1.7

We are having a problem with TConstruct Smelterys. Over last week we have had two server crashes caused on two chunks.

People using Smelterys causing lava overflow crash the server, once you go near that chunk the server crashes, please see error below;

Here's how to fix it. Go into MCEdit and delete the offending smelteries(Compensating the owners of said smelteries of course), then sternly warn your players not to let their smelteries get too full.

Please see attached crash report, is there any other way to resolve the issue to stop it happening? without banning smellteries?

Also,

We are getting another crash randomly see below;

You don't have to ban smelteries. Just warn your players of what happens if they aren't watched.
The first crash report is the same as the one you posted in the first post. The second one is caused by dynmap.

I have fixed the issue with Dynmap, however this TConstruct problem is a huge issue for us. People do not realise they are doing this and causing the crashes, we have told people and put up server messages however there will always be someone who does not listen, or purposely intends to crash the server.

Once the server crashes when no admins are online there is nothing we can do and this is effecting our uptime, if we was to follow your logic on every problem I would not have a ban list for server crashing items or greifing items as I could tell players all day long to not do this or that, but they will not listen at end of day.

Please could you provide a solution to resolve the issue? or if anyone else on the forum can.

Thanks in advance.

Well, there is no way of keeping it from happening aside from banning smelteries(or disciplining the players who do this).

Why would you discipline a player over something they can't control? LOL...

You can also fix this.

Disable the placement of flowing metals. Use TekkitCustomizer and add this below.

    PlacementBanned:
    - 1479:*:TConstructFlowingLiquidFix

Also some liquids from TConstruct don't render correctly with buildcraft pipes and cause server/client crashes.

You have two choices besides patching the mod.

1. Make a plugin to disable placement of BuildCraft pipes next to smeltery controller.
( Lots of plugin examples on Google )
2. Make a plugin that scans the affected area and replace the pipes with air/stone/whatever.
( I made this, its crude but works; source here - > http://pastebin.com/raw.php?i=stu0Qv4p

Over something they can't control? They can control it just fine! By not going nuts with the smeltery.

Why am I not aware of this? I'd rather just fix it in BuildCraft... (or ask boni to fix if I figure out it's a TCon bug instead)
