mapserv binary file changes?

[Vincent J. Troisi]

Has anyone experienced this problem?

Periodically, the mapserv binary (executable) changes. The file
size is the same, and the time stamp is the same as when the
file was placed in the directory, and the stats on the file
show no modification to the file, but...the md5sum is different
than the original file and the binary, mapserv, is unuseable.

Thoughts...
