The problem is that pfDataPools must occupy the same
address space in every process (see usinit(1)). This
means that pfDataPools should be constructed early in
the application and in the same order in all
applications. It's OK to make calls like pfNotifyLevel
and pfAttachDPool before pfInit().

In the next release, this error will print out:

Performer Warning (16): pfAttchDPool: could not map datapool /usr/tmp/dataPool.pfdpool into required address.
Try calling pfAttachDPool earlier in the application.

  Subject: pfDataPools

  I've been having some problems using pfDataPools. In most cases I get an error
  telling me that the pfDataPoolAttach call failed. The only way I can successfully attach is if the "attach" call is made before pfInit() (which is a violatioin of Performer rules), and if I am not using a loadFlt or loadFile call. Has any one been able
  to use this function successfully? I've tried on both Irix 4 and 5 versions of
  the os. I also passed a sample program demonstrating my problem to the Performer info hotline team, but it's been over a month and a half and they still t returned an answer.
  Can anybody help me out here?
