Problem with IMG files! Is there a limit on the number of img in the game? (Grand Theft Auto: San Andreas)

Once again, added another gta3.img archive(by using img clone)...the fourth archive account.
And it is the fourth archive of the problems started. After loading the game immediately crashes error.
With the previous three archives, everything was fine. The game worked perfectly, but they are almost huddled up to 2GB.
And here's the fourth such quirks.
What could be the problem?
Or in GTA SA there are restrictions on the number of img archives( as well as with a weight of the original archives?)
