If you have checksum errors reading data from disk, you have much worse issues than ram corruption. Any program you launch will probably be corrupted.

Although if you do swap on a server (and you should), the swap needs to be on a raid, otherwise your server will crash on a disk error.

Swap on a server is not meant for handling low memory issues, instead there's tons of data on a server that's almost never used, so instead swap that out and make more room for cache.
