I have a weird issue with Minecraft locking up after a while. I had this in the past with my personal modpacks (that also included Thaumcraft 3), but had forgotten about it for a while because I started to play a new modpack composition that didn't have Thaumcraft 3 included. Anyway, after adding Thaumcraft 3 I am experiencing it again.
After playing a while, Minecraft stops responding. There is no crash or log update from that moment onwards. Also no memory usage problem. My toon animation is still going and I can move it, but there are no world updates (chests/doors won't open, blocks won't break) When I then try to close Minecraft normally , it keeps hanging on 'closing internal server' (apologies if I did get the exact msg wrong). The last entry in MultiMC log is always : ' [ForgeModLoader] [THAUMCRAFT] Restoring client configs.' .
Now this could all be just a coincendence, and to be honest I find it very difficult to reproduce the bug. There is no clear action that triggers it as far as I can tell. But I only noticed a possible connection to TC3, because I didn't have this problem for a while, untill I added TC3 the other day. While I had this same issue a while ago with a personal modpack with TC3 included and it happened in the exact same way.
I am at a loss here and this is the only lead I have atm for this particular issue. I'm using Windows 7 and 32bit java.Is it possible that there is an issue with node updates?
