Crash during heavy nuke/missile saturation: Infinite loop error in `RecordNukeTarget`

[wafelmolt]

Description

The game consistently crashes during intense late-game scenarios involving massive nuclear missile launches. Analysis of the log files reveals an infinite loop error triggered within the RecordNukeTarget function of M28AI.

The AI repeatedly fails to record nuke missile locations, likely due to a failure to parse the specific projectile data in a high-intensity combat situation.

Steps to Reproduce

1. Run a match with M28AI enabled along with BlackOps FAF: Merged and Total Mayhem mods.
2. Progress to the late game where high volumes of tactical and strategic missiles are being fired simultaneously.
3. Observe the logs as they flood with Potential infinite loop, aborted recording nuke missile location warnings.
4. The game eventually crashes as the Lua stack/log might saturates (?).

Log Snippet

warning: false  M28ERROR Count=1: GameTime 5741: Potential infinite loop, aborted recording nuke missile location
warning: stack traceback:

Environment

• Game Version: 3836
• M28AI Version: 305
• Active Mods: Quantum Resource Generators, Total Mayhem, Patch19Core, BlackOps FAF: Merged, Shields Enhanced

Additional Context

This issue seems triggered by the interaction between RecordNukeTarget and the high volume of projectiles. It appears the logic struggles to handle the sheer number of events during projectile firing, leading to the aborted loop and subsequent crash.

Additional infos:

If I remember correctly, it crashed just seconds after I launched simultaneous missiles with the distribute order feature (shift+G).

Thanks, I've made a note to look into (for future reference it's best to send me a message on discord for a quicker response as I don't tend to check my email notifications that often)

Do you know how many simultaneous nuke launches there were when the error appeared in the log?

In particular, if it could've been 30+ nukes, then it could well just be that the simultaneous launches put a heavier toll on the memory usage which caused the crash. If you have task manager open and it shows the game going near 2GB (likely with other sim mods in long games) this can cause a crash.

Hello. Thx for the feedback.

I guess it was quite big launch (like 26 nukes, something like that). I guess you migh be right about OOM kill. Meanwhile I tweaked the launch settings (run on linux) to enhance memory cap and there wasn't more crash for a while.

However, the M28ERROR in the snippet is still real 👍
