Limit of data in a data file

Greetings,

I have a doubt about the use of a data file. Recently, i was simulating a mill, and instead of use the particletemplate/sphere keyword, i was using a data file to load all the particles. The total amount of particles that i used was 1344278. However, in a second simulation, i increased the number to 1728272, and when compile LIGGGHTS, the program generated a error and then it close unexpectedly.

My question is if there is a limit of particles in a data file, or is a problem with the computer that i use for simulations. My computer has 8 processors.

Thanks and i hope for an answer

Best regards.
Nicolás
