When I try to create a world in my new modpack it freezes on Converting World and eventually crashes. Sorry if this is obvious but I am a noob at debugging.
I've set the memory allocation to 6 GB and downloaded the newest version of Java 64 bit but it just freezes and never even crashes. The last thing in the log file is "Unable to find spawn biome". Any help would be appreciated.
I'm wondering if this is being caused by buggy mods because there is no reason for the game to crash with 4 GB of memory allocated and lock up with 6. The seed itself may partially be at fault; when you see "unable to find spawn biome" this means that the game could not find a biome for the player to spawn in (plains, forest, jungle, taiga) within 256 blocks of the origin and as a result it attempts to find a suitable spawn point by randomly checking up to 1000 points for an exposed grass block above sea level (if the chunk at 0,0 has grass it will spawn you at that spot, otherwise it runs until it either hits 1000 checks or finds grass in a chunk).
By "buggy mods", and how this relates to the game being unable to find a spawn point, many world generation mods are poorly written and cause adjacent chunks to load/generate when placing features, resulting in runaway chunk generation that can cause all sort of problems from very slow world generation or chunk loading up to running out of memory or stack overflow - especially when the game is randomly generating hundreds of chunks all over the place as when it is searching for a suitable spawn point (even in vanilla this can double or triple the number of chunks loaded during world generation):
I can't say which mod(s) may be responsible (the Reddit link uses the "All the Mods 2" modpack as an example) but this is a pretty common issue and having multiple mods with it aggravates the situation.

The latest.log file is here:

Thank you in advance!
I don't see a crash. Check your "crash-reports" file located in .minecraft and tell me if you got a crash?
This is the crash report here:

I have tried removing Optifine but that hasn't worked. By the way I'm using Technic to do this.

TheMasterCaver's First World - possibly the most caved-out world in Minecraft history - includes world download.
TheMasterCaver's World - my own version of Minecraft largely based on my views of how the game should have evolved since 1.6.4.
Why do I still play in 1.6.4?
Thank you for all your help. I have identified that the buggy mod was Mo' Creatures and I removed it. The pack works now!
