Volume bitmap needs minor repair for orphaned blocks

Every once in a while I'll verify permissions using disk utility. A few weeks ago I ran the verify disk and it came up with an issue like the one below. I repaired it and now it has happened again. This is the 3rd time actually. Is my SSD having issues and need replacement or is this common?

Verifying volume “Macintosh HD”

Checking Journaled HFS Plus volume.

Checking extents overflow file.

The volume Macintosh HD was found corrupt and needs to be repaired.

Error: This disk needs to be repaired using the Recovery HD. Restart your computer, holding down the Command key and the R key until you see the Apple logo. When the OS X Utilities window appears, choose Disk Utility.

Thanks.
