Let&#x27;s say you distribute a binary over NFS -- compile some C or C++ or whatever you like.  Then various hosts run &#x2F;path&#x2F;to&#x2F;binary.  At some point, the NFS server changes that file out from underneath those hosts, because, well, it can.  The usual &quot;text file busy&quot; you&#x27;d get when trying to do that on a local filesystem never happens.<p>At some point after that, the hosts running the binary will try to page something involving that binary and will SIGBUS and die.<p>That&#x27;s just one of many failure modes.
