Random Server Crashes

So randomly my server crashes and everyone loses connection to the server. Everything works…as in jobs/weapons, etc. Everything runs smoothly but it randomly crashes.

Here’s the console output right before the crashes:

CreateFragmentsFromFile: ‘user_custom/8c/8c87000b.dat’ doesn’t exist.
CreateFragmentsFromFile: ‘user_custom/15/154c5ec2.dat’ doesn’t exist.
CreateFragmentsFromFile: ‘user_custom/81/81739bcc.dat’ doesn’t exist.
CreateFragmentsFromFile: ‘user_custom/33/334662aa.dat’ doesn’t exist.
CreateFragmentsFromFile: ‘user_custom/77/772c27b4.dat’ doesn’t exist.
CreateFragmentsFromFile: ‘user_custom/a4/a45752ef.dat’ doesn’t exist.
CreateFragmentsFromFile: ‘user_custom/8c/8c87000b.dat’ doesn’t exist.
CreateFragmentsFromFile: ‘user_custom/15/154c5ec2.dat’ doesn’t exist.
CreateFragmentsFromFile: ‘user_custom/81/81739bcc.dat’ doesn’t exist.
CreateFragmentsFromFile: ‘user_custom/33/334662aa.dat’ doesn’t exist.

Everything before it is normal stuff, like people joining, respawning, etc. Just out of the blue this stuff pops up and server goes under. I have no clue what the problem is, but my hoster believes it’s “software issues” while I believe it could be corrupted data.

Any ideas? I have no clue what that file is.

Wrong section.
