Details:

Hello 

If the binary name of the xrootd or the cmsd are using a .postfix extension
the command name seen by ps has the dot replaced by a space. For example:
 % xrootd.test -c .... 
  would show up in ps as:
 % ps -ef | grep xrootd 
   xrootd test -c .....

The origin of the problem is in XrdConfig.cc (for xrootd):

  if (dotrim && *dfltProt != '.' )
      {char *p = dfltProt;
       while (*p && *p != '.') p++;
       if (*p == '.') *p = '\0';
      }
   Firstcp = Lastcp = new XrdConfigProt(strdup(dfltProt), 0, 0);

dfltProt points to the file basename in argv[0] and in the if statement the
dot after xrootd gets replaced with a space. Looks like on Linux argv is
global and used by the kernel to determine the program name. 
As mentioned this happens for the xrootd and cmsd. 
On Solaris this does not happen.

Cheers,
  Wilko
