I've gotten a little further. 
 
The problem affects regular Intel P4s as well, 
so it's not Xeon specific. 
 
After compiling ipop3d from scratch, I stepped 
through the execution with gdb.  The problem 
occurs when ipop3d looks up two passwd 
entries: 
 
                /* #public namespace */ 
  if (!publicHome 
         && (pw = getpwnam ("imappublic"))) 
    publicHome = cpystr (pw->pw_dir); 
                /* #shared namespace */ 
  if (!anonymous 
         && !sharedHome 
         && (pw = getpwnam ("imapshared"))) 
    sharedHome = cpystr (pw->pw_dir); 
 
 
If either of these users does not exist, then 
ipop3d goes into loop mode, and consumes all 
available memory.  If both users exist, ipop3d 
functions correctly. 
 
At this point, I don't know if the problem is 
with ipop3d or glibc or something else.
