   aye, gotcha. i was misleaded by the shmmax value, but it appears i
   need to bump at least SEMMNI (11 by default). savvy*

   And i was fortunate enough to trigger another condition on the linux
   box, where the problem was not due to ipcs thresholds reached, but
   rather to me having bumped the BUFFLEN value to x5 the default.

   All is functioning great now that i decreased it to the default.

   my next problem will be to find colors that mix well and are readable
   for that many souces ... :)

   Sorry for the noise Peter, and many thanks, as usual
