Help with figuring out an error

So this error keeps occurring:

CreateFragmentsFromFile: ‘user_custom/17/174e6558.dat’ doesn’t exist.

I’m not sure what is causing this, but I get a minor lag spike when it happens and it happens at least 5-6 times before stopping.
Any help will be much appreciated, I’m running a DarkRP 42 slot server on rp_downtown_v4c_v2.
