Corrupted game files or outdated support software can cause memory allocation to fail.

The most effective community-verified "best" fix for getting past a specific crash point (like the LA mission) is to drastically lower the game's resource demands.

BO2 Error: Failed to allocate from state pool :: Call of Duty

The error in Call of Duty: Black Ops II is a notorious memory-related bug that typically occurs during specific campaign missions (most notably "Cordis Die" in LA) or when purchasing perks in Zombies. It stems from the game engine's inability to manage resource allocation correctly, often triggered by modern high-resolution settings or specific in-game events. 1. Reduce Graphics and Resolution

: While drastic, choosing to shoot Harper instead of Farid has been reported to bypass the state pool crash in the subsequent LA mission. 4. Verify Game Integrity and Update Redistributables

: Locate the game's executable files (usually t6sp.exe for singleplayer, t6mp.exe for multiplayer, or t6zm.exe for zombies) in your Steam library folder.
