Random crash with multiple PF source

[renochew]

I got a situation. I have three PF source, each have its own Position Object node and ABurn node, I got random crash during ABMap calculation, I tried a lot of way debugging it with no success, they crash in different frame number. I can render out each of them separately without problem, so I think maybe the particle count is to much (around 5k), but then I try grouping all three position object into one PF source and adjust accordingly the amount of particles, it render without problem. But of course I lost individual control.

The 3 original particle system and AB setup are very similar, I separated them just for fine tuning things. What is the possible cause of this problem?

Thanks in advanced.
