hi,

Does someone has already had that kind of problem.
Any explanation will be appreciate.

When I changed pfPhase mode from PFPHASE_LOCK to PFPHASE_FREE_RUN, my
application freeze. In fact the APP process seems stalled and the DRAW
process looping. I'm running in APPCULL_DRAW multiprocess mode. And the
pfPhase call is done just before pfAppFrame in the main loop.

Here are the stack of each process.

APP:

/xlv51/6.5.10f/work/irix/lib/libc/libc_n32_M4/sys/usync_cntl.s) not
available for Process 69713
