The computer is a VPS from Vultr. They tell me that "since it is loaded into RAM and not really a drive, nothing on the host would be causing this."
One particular file, my zone file, will come up corrupted for no reason. I have had to replace it from backup a couple of times. I have found other corrupted files (one or two) over the past couple of months. But I am in my dns a lot a the whole world knows when this file explodes/dies.
No errors in dmesg, I ran a file system check at boot and 2 weeks later, same thing.
Where would I look to find the root cause of this file corruption and fix it? . Lots of output
