Hello,

I was wondering why the MX sync was not working at all for me.
I got always the error message in the syslog which is in the subject of this
mail.
Now I found the reason of this bug^H^H^Hfeature.

If a stream is open for update operation between read and write operation
flush operation has to be executed.
"man fdopen" on Tru64 UNIX says among others:

 "Also, an input operation cannot be directly followed by
  an output operation without an intervening flush or file positioning
opera-
  tion, unless the input operation encounters the end of the file."

So I attach now the patch which fixes that problem. I do not know is anybody
else encountered this?

The change from strtok to strtok_r is an artefact of my debugging but I
consider it worthwhile to keep.
It is generally safer to use a re-entrant version of the function in a
thread than the non-re-entrant.
Actually it is not a problem now but it might become later if the code
evolves further.

Bests,
Attila
